To prepare 5% 2C8-diene-1% 2C2% 2C3% 2C4-tetraaminoisosquare photocysteine anhydride, the following method can be used.
First take an appropriate starting material, which needs to contain a group capable of deriving the target structure. Usually start with unsaturated hydrocarbons or nitrogen-containing compounds with specific substituents. After ingenious reaction design, the unsaturated bond and the nitrogen-containing part gradually build the skeleton of the target molecule.
One method can first introduce the amino group at a suitable position through nucleophilic substitution reaction. Select a halogenated hydrocarbon or sulfonate with suitable activity and react with ammonia or amine compounds under appropriate conditions. The conditions of the reaction are crucial, and the temperature, pH and reaction time need to be precisely regulated. Generally speaking, mild alkaline environments, such as aqueous solutions of potassium carbonate or sodium carbonate, can react at moderate temperatures (such as 50-80 degrees Celsius) to enable nucleophilic substitution reactions to proceed smoothly.
When unsaturated bonds are formed, the elimination reaction is often achieved. Alcohols or halogenated hydrocarbons can be used to remove small molecules (such as water or hydrogen halide) under basic reagents and appropriate heating conditions to form carbon-carbon double bonds. Alcoholic solutions of sodium hydroxide can be selected for basic reagents, and heated to a reflux state to promote the elimination reaction to occur and construct a 5% 2C8-diene structure.
During the synthesis process, the reaction process needs to be closely monitored. Thin-layer chromatography (TLC) can be used to observe the consumption of raw materials and the formation of products. According to the location and color changes of the spots on the TLC plate, determine whether the reaction is complete. When the reaction reaches the desired stage, it needs to go through the separation and purification step.
The commonly used separation method is column chromatography. Silica gel is used as the stationary phase, and a suitable eluent, such as a mixed solvent of petroleum ether and ethyl acetate, is selected to achieve high-efficiency separation according to the difference in the polarity of the product and impurities. Finally, the product was further purified by recrystallization and other means to obtain pure 5% 2C8-diene-1% 2C2% 2C3% 2C4-tetraaminoisosquare cysteine anhydride. The whole synthesis process requires fine operation, paying attention to the condition control and product monitoring at each step, in order to successfully achieve the preparation of the target product.

What is the market price of 5% 2C8-diene-1% 2C2% 2C3% 2C4-tetraaminoisoprene photosuccinate amber?
In Guanfu City, the price of various materials is often different due to changes in time, place, quality and supply and demand. This 5% 2C8-diene-1% 2C2% 2C3% 2C4-tetraaminoisoprene photosuccinate amber is an unusually easy product. Its preparation may require exquisite methods, and the raw materials used may also be rare.
If in the prosperous city of Kyoto, there are many businesses and many traders, when supply and demand, the price may be slightly higher. If the quality is high, the price per catty may reach tens of gold; if the quality is slightly inferior, it will also cost more than ten gold.
And in remote cities, the transportation is inconvenient, and merchants are rare. This thing may be hard to find. Even if it is there, its price will be high, because the transshipment is difficult and the cost is doubled.
Moreover, in times of abundance, the material resources are rich, and all workers are prosperous. These materials may be slightly increased due to the production, and the price may drop; if it is a famine, everything is difficult, the material resources are scarce, and the price will rise, which is not reasonable.
As for the exact number, it is difficult to determine it quickly. The situation in the market is fickle, and you can only know the current price if you are close to the market and consult all merchants.

5,8-Diene-1,2,3,4-tetraaminoisosquaric acid dicamide is a rather special chemical substance. Its storage conditions are crucial to the stability and effectiveness of this substance.
According to the concept of "Tiangong Kaiwu", everything needs to be properly placed to maintain its properties. 5,8-diene-1,2,3,4-tetraaminoisquaric acid dicamide should be stored in a cool and dry place. Because the temperature is too high, or the chemical reaction of this substance occurs, its structure is damaged, and its original characteristics are lost. And humid environment is not advisable, moisture or interaction with the substance can cause adverse reactions such as hydrolysis.
Furthermore, this substance should be placed in a dark place. Light can be used as an energy source to induce luminescent chemical reactions, which affect the chemical structure of 5,8-diene-1,2,3,4-tetraaminoisosquaric acid dicamide. Therefore, it needs to be stored in opaque containers, such as brown glass bottles, which can effectively block light and reduce the probability of photochemical reactions.
In addition, the storage place should be kept away from fire sources and oxidants. 5,8-Diene-1,2,3,4-tetraaminoisosquaric acid dicamide may be flammable to a certain extent, and it is easy to cause fire when exposed to fire sources; and the contact of oxidants with it, or triggering a violent oxidation reaction, not only endangers the preservation of the substance itself, but also may lead to safety accidents.
In short, in order to properly store 5,8-diene-1,2,3,4-tetraaminoisquaric acid dicamide, it must be cool, dry, protected from light, and away from fire sources and oxidants, so as to maintain the stability of its chemical properties for subsequent use.
