Isoquinoline, 6-bromo-1,3-dichloro-

What are the chemical properties of this product? "Tiangong Kaiwu" has a saying: "Silk, hemp, furs, and browns in the world all have qualities, so that the special color can still be seen. I don't believe it if I say that the creation of things is not laborious." However, among all kinds of materials, each has its own unique chemical properties.
In terms of common metal products, gold is very stable in nature. Although it has passed through the years, it is difficult to combine with other things, so it can be preserved for a long time, and the color does not change. The so-called "real gold is not afraid of fire refining" is not a lie. Under the chemical action, it is mostly inert and not easy to be oxidized and eroded.
Iron is not the same. Iron is easy to react with oxygen and water in the air and rust. This is the oxidation process of iron. Rust is actually an oxide of iron. Its loose texture cannot prevent iron from further reacting with external substances, so iron often needs proper maintenance and protection to avoid rust.
Looking at ceramic products, their main components are mostly minerals such as clay. After high temperature firing, the mineral components in the clay undergo complex chemical reactions to form hard and chemically stable substances. Ceramics are resistant to acid and alkali corrosion, and their chemical properties are relatively stable. They can be used as containers or decorative beauty. They have survived for thousands of years and are not damaged. The cover is stable because of its chemical structure after firing.
And like all kinds of fabrics, silk, from the silk cocoon twisting, the main component is protein, with good flexibility and luster. However, its chemical properties make it susceptible to moth-eaten, need to be properly preserved. Hemp is derived from plant fibers, with slightly stronger chemical stability and good moisture absorption.
All these, different products are due to their unique chemical properties, in order to show the world's different characteristics and uses, the beauty of creation is amazing.

The main purpose of this product is to cover multiple ends.
It can be used for repair and construction. In ancient palaces and pavilions, if there is any decay or damage, it needs to be repaired and reinforced with materials. If the beams and columns are decayed, new wood must be replaced. This product may be used to cut into beams to bear the weight of the house and make it as stable as ever; if the walls are peeled, use it to reconcile the mortar and apply it flat to make the walls strong and beautiful.
It is also indispensable for the production of utensils. If you want to make exquisite wooden ware, you need to use it to sawing wood to make it into suitable plates, wooden strips, and then carving and splicing to form tables, chairs, and other objects; when casting tools, it can be used to make molds, so that metal solutions can be injected into molds to create tripods, bells and drums, etc., or for sacrificial rituals, or for daily use.
Furthermore, in agricultural production, it also has its uses. The construction of farmhouses requires this product to build a frame, shelter from wind and rain, and provide habitat for farmers and livestock; the manufacture of agricultural tools, such as ploughs, waterwheels, etc., also relies on its cutting and polishing materials to make them have a suitable shape, which helps farming irrigation and improves the efficiency of production.
On top of the military, it can also play a role. The construction of camps requires the construction of fences and barriers for defense; the construction of weapons, such as the production of bows and crossbows, requires the processing of wood to make the bow body tough, the crossbow arms are used together, and the cutting of arrows is also inseparable from this product to ensure the sophistication of weapons and enhance the combat effectiveness of the army.
In short, this product is widely used and is essential in construction, production, agriculture, and military affairs.

There is a way to make this thing in ancient times. The completion of a good thing depends on the thinking of the skilled craftsman, and the art is based on the material, and each uses its own use to achieve its wonders.
Where this thing is made, the first priority is to choose the material. The material must be firm and of good quality before it can be used. Looking at the ancient times, in the selection of materials, be cautious. Wood is carefully textured, stone is firm and flawless, and metal is pure and not complicated. The quality of the cover material is related to the success or failure of the thing. This is the foundation of the production of things.
The second is the method of fabrication. The craftsman handles the utensils, transports the catties into the wind, and carves according to their shape. Whether it is cut into shape, or cast and molded into shape, there are fixed rules. Its ingenuity and wisdom, depending on the size and simplicity of the object, apply different techniques. If it is a small piece, it must be carefully crafted, and it can be seen in the slightest; if it is a giant object, it must be planned and orderly step by step. And the ancient man-made objects often took nature as a teacher, imitating the shape of heaven and earth, and the state of all things, so that the made objects were both practical and beautiful.
Furthermore, the decoration process should not be ignored. Or paint to add color, or inlay to add splendor, or engrave to enhance text. The lacquer takes its luster and is warm, which can protect the object and is beautiful; the inlay uses the genus of gold, jade and gemstones to make it shine; the engraver leaves characters and engravings on the object to give it cultural connotation. The three are used together to complement each other and multiply the charm of the object.
As for the mastery of the heat, it is also the key. When smelting, the size and duration of the fire are related to the texture of the object. If the fire is fierce, the object is easy to melt, and if the fire is small, the quality is difficult to be pure. The craftsman uses experience and eyesight to adjust it in a timely manner to make the object just right.
Overall, the system of this object, the selection of materials, fabrication, decoration, and heat are all interlinked and indispensable. The ancients passed down this method of making things with their wisdom and skills, so that future generations could get a glimpse of the delicacy of the ancient times.

Looking at today's city, if a product wants to show its competitiveness, it can be compared to the ancient theory of business. The city of Fu is like a battlefield, and the competitiveness of the product is related to the rise and fall of life.
If you want to discuss the competitiveness of this product, you should observe its quality. Gu Yun: "If you want to be good at something, you must first sharpen its tools." The quality of a product is the foundation of its foothold. Like the edge of a good sword, it needs to be tempered. If the quality is not good, even if you have the art of persuasive words, it will be difficult to establish a long-term presence in the city. Therefore, you must study the craftsmanship and select excellent materials, so that the product is solid and durable, and the quality is high, in order to win the hearts of the people.
Furthermore, look at it as new. The wise merchants of ancient times often think about changes and seek The market conditions are ever-changing, and the good of people is still changing. If a product is conservative, it must be abandoned by the market. When innovation is the key, or the function is new, or the shape is different, if it can introduce new ideas and be original, it will stand out from the crowd. You can attract attention and compete to buy it.
And look at its price. "If the price is appropriate, you will sell quickly, and if the price is high, you will have few customers." The way of pricing, you need to weigh the pros and cons. Don't be greedy for big profits and lose customers, and don't sell at a low price and damage yourself and break the market rules. When the situation is judged, the price of the same kind is observed, the cost is measured, and the price is set at a moderate price, so that the benefits and the market can both benefit.
Look at its reputation. Reputation is also the wings of the product. "Everyone's mouth is full of gold, and the bones are destroyed." If the product is well-known in the market, it will be famous far and wide, and everyone will believe it. Therefore, when the after-sales service is emphasized, it is good to accept customers' words, and if there is a mistake, it will be changed, so as to make customers happy. In this way, word-of-mouth is passed down, and its competitiveness can become more and more prosperous.
To sum up, if a product is in the market, if it wants to be competitive, it needs high quality, innovation, affordable and good reputation. These four have both, like the equipment of a boat and the spare wheel of a car, it can travel freely in the market, and it will be undefeated in the sea of commerce.

This product is related to safety, and many matters need to be paid attention to. Bear the brunt of it. When handling this thing, you should take stability as the priority. As "Tiangong Kaiwu" says: "Where you make things, you must first seek stability. If you are stable, things will be easy to achieve, and if you are unstable, things will be difficult to achieve." When operating, you need to keep your hands steady and your heart steady. Don't panic, so as to ensure smooth operation and avoid accidents.
Furthermore, it is related to the environment. The environment in which this thing is located should be dry, ventilated, and protected from moisture and occlusion. "Tiangong Kaiwu also has a saying:" The existence of things depends on the environment, and the environment is dry, and the environment is not easy to perish. "Moisture can easily cause corrosion and damage to utensils, and if you are blocked, the gas will not circulate, or there will be hidden
Repeat, protective gear is indispensable. When operating, you must wear suitable protective clothing, goggles, gloves, etc. This is a comprehensive measure to protect yourself, just as the ancients said: "If you don't predict it, it will be useless." Do a good job of protection in advance to avoid injury and damage in the event of an emergency.
In addition, knowing the performance of this object is the key. When studying its instructions carefully, clarify its functions and limits. The "Tiangong Kaiwu" also emphasizes the importance of understanding the characteristics of utensils: "Only by knowing the nature of objects can you make good use of them." If you don't know its nature, act rashly, and you may cause disaster.
And maintenance should not be ignored. Check and clean this object regularly. If there is any damage, repair it immediately. The ancients said: "If you want to do something good, you must first sharpen your tools." Keep it in good condition before it can be used for a long time and safely.
The operation process must be strictly followed. Follow the prescribed steps and do not change it without authorization. This is the experience of predecessors. If you follow it, you will be safe. If you go against it, you will be at risk.
Finally, pay attention to others approaching. When operating, inform others to keep a safe distance and do not let others approach rashly, so as not to harm the innocent. This is an important precaution for product safety and must not be slack.
