1% 2C3 - Sandalwood - 2 - Tannic Acid has a wide range of properties.
Sandalwood is fragrant and rich. Its taste is fragrant and long-lasting. It burns well and is fragrant in the room. It can be used in a safe and multi-fragrant way.
For tannic acid, its color may be light to brown. Tannic acid is soluble in water, ethanol, etc., and has a good solubility in different solutions. Its chemical activity can combine with gold and produce a soluble solution. This property is often used in tanning, making leather soft and resistant to corrosion.
Tannic acid is also original, and can be oxidized in case of oxidation, and the color is dark or dark. In an acidic environment, tannic acid can be biodegradable, and its acidic properties can be reversed.
Tannic acid can also react with proteins to generate insoluble sedimentation. This property can be used for proteins in sedimentation solutions, and it is also useful in the fields of raw materials, food processing, etc.
Of course, the fragrance properties of sandalwood and the physical properties of tannic acid are all used in different fields. It is used in the world and has also been observed by the ancients. It is used in life to add convenience and emotion.

1% 2C3-pyridine-2-carboxylic acid, also known as 2-pyridinecarboxylic acid, has many synthesis methods, which are described in detail today.
First, 2-methylpyridine is used as the starting material and can be obtained by oxidation reaction. This oxidation process can be obtained by chemical oxidants such as potassium permanganate, potassium dichromate, etc. Taking potassium permanganate as an example, in an alkaline environment, 2-methylpyridine reacts with potassium permanganate, and potassium permanganate oxidizes methyl to carboxyl groups to obtain 2-pyridinecarboxylic acid. This reaction condition is relatively mild, but attention needs to be paid to the post-reaction treatment to remove impurities such as manganese salts. < Br >
Second, using pyridine as a raw material, lithium atoms are first introduced through a lithium reaction, and then reacted with carbon dioxide. Pyridine reacts with butyl lithium at low temperatures, and hydrogen at a specific position on the pyridine ring is replaced by lithium to form a lithium-based pyridine intermediate. This intermediate reacts with carbon dioxide, which is inserted into a lithium-carbon bond, and after acidification, 2-methylpyridine acid can be obtained. This method is slightly complicated, but the selectivity is quite high, and the reaction check point can be precisely controlled.
Third, using 2-cyanopyridine as a raw material, it is prepared by hydrolysis reaction. 2-Cyanopyridine is hydrolyzed under acidic or alkaline conditions, and the cyanyl group is converted to a carboxyl group to obtain 2-pyridinecarboxylic acid. If hydrolyzed under acidic conditions, strong acids such as sulfuric acid are commonly used; if under alkaline conditions, strong bases such as sodium hydroxide are commonly used. After hydrolysis is completed, a pure product can be obtained through acidification or neutralization steps.
Fourth, with the help of microbial conversion method. Some microorganisms have specific enzyme systems that can catalyze the conversion of specific substrates. For example, some bacteria or fungi can use specific nitrogen-containing heterocyclic compounds as substrates and catalyze them to convert them into 2-pyridinecarboxylic acid through enzymes in the body. This method is green and environmentally friendly, and the conditions are mild. However, it requires harsh requirements for microbial culture and reaction conditions, and

1% 2C3-musk-2-ricinoleic acid is above the market, and its price range is quite relevant factors, so it is difficult to determine the exact number. Musk, a precious spice and medicinal material, is rare and rare in the world. Ancient musk, mostly taken from musk sachets, but musk species are now mostly protected beasts, hunting is prohibited, and the price of musk has always been high. Musk in the market today, either artificially made or stored in the past, has different quality and prices. Roughly speaking, high-quality natural musk can cost thousands of yuan per gram; synthetic, although the price is slightly inferior, it is not cheap, ranging from hundreds of yuan per gram.
As for ricinoleic acid, it is an organic acid obtained by hydrolysis of castor oil. It has a wide range of uses and is used in chemical, pharmaceutical, textile and other industries. Its price varies according to market supply and demand, quality specifications. Ordinary quality ricinoleic acid, the price per ton may be in the thousands to more than 10,000 yuan; if it is high purity, special specifications, the price or higher, up to tens of thousands of yuan per ton.
The city changes, and the business situation is fickle. The price of the two also moves at any time. If you want to know the exact number, you must carefully examine the market situation and consult the experts.

The storage conditions of 1% 2C3-musk-2-valerian acid are related to the preservation of its quality and the effectiveness of its use. Musk, a precious fragrance and a good medicine, valerian acid is one of its important ingredients, so the preservation method must be cautious.
First words Storage temperature and humidity. It should be placed in a cool and dry place to avoid hot topics and humidity. If it is in a warm place, the valerian acid in musk may evaporate and dissipate due to heat, causing the purity of its fragrance and the effect of medicine to be impaired; and if it is humid, it is prone to mildew and damage its quality. It is best to keep it in a cool (about 15-25 degrees Celsius) and dry (relative humidity 40% -60%) place.
Times and storage containers. When it is sealed and protected from light. Musk is volatile, and valerian acid is the same. Open utensils can easily cause its aroma to escape, so it is better to use airtight porcelain bottles and glass bottles to prevent aroma leakage. And valerian acid is sensitive to light. Under light, or its chemical structure changes, which affects the quality, so the utensils should be placed in a dark place, away from direct sunlight.
Furthermore, do not mix with other things. Musk has a strong aroma, and valerian acid also has a unique smell. If it is stored with odorous things, it is easy to mix odors, damage its original fragrance, and chemically react with other things, damaging its composition and effectiveness. Therefore, it must be stored separately to keep it pure.
In short, if you want to store 1% 2C3-musk-2-valerian acid well, you must pay attention to temperature and humidity, containers and storage environments, so as to maintain its quality for a long time without losing its fragrance and effectiveness.
