2-[(4-nitrobenzyl)sulfanyl]-4,5-dihydro-1,3-thiazole

"Tiangong Kaiwu" says: "All lime is used by fire. After it is formed, it will not be damaged forever when it enters the water. Hundreds of millions of boats, hundreds of millions of walls, choking gaps to prevent adultery, it must be done." Lime, its main uses are as follows.
One is used in the construction field. For example, when building walls, lime is combined with other materials to enhance the firmness of the wall. "Where the wall soil is used to fill the joints, the ash will stick to the brick or stone, and it will last for a long time." Mixing lime with sand, clay, etc., and applying it to the wall, not only makes the wall smooth, but also resists wind and rain erosion and protects the wall. In the construction of large buildings, such as palaces and city walls, lime is an indispensable material, so that the building will not fall over the years.
Second, it also plays an important role in the manufacture of boats and boats. "The bilge and gaps in the boat must be filled with lime mixed with hemp silk, tung oil and other materials to prevent water leakage." Ships have been sailing in the water for a long time, and if the gaps in the bilge and wooden boards are not properly handled, it is easy to seep water. After lime is mixed with hemp silk and tung oil, it can effectively plug the gaps, prevent the intrusion of water, and ensure the safe navigation of ships in the water. Whether it is inland shipping or ocean sailing, ships rely on it.
Third, it also has auxiliary effects in agricultural production. Although "Tiangong Kaiwu" does not emphasize it, in later practice, applying an appropriate amount of lime to farmland can adjust soil pH, improve soil structure, and create a good environment for crop growth, which helps to increase crop yield to a certain extent.

In the Taoist classic "Tiangong Kaiwu", these substances have their own unique chemical properties.
2- [ (4-aminopyridine) carbonyl] -4,5-dihydro-1,3-oxazole, in this compound, the nitrogen atom of the aminopyridine part has certain basic properties and can react with acids to form salts. Its carbonyl properties are active and can participate in nucleophilic addition reactions, such as the formation of acetals with alcohols under specific conditions, or the reaction with amines to form corresponding imines. The structure of the dihydro-oxazole ring gives it certain stability, but in strong acid or strong base environments, ring-opening reactions may occur, triggering structural rearrangements. < Br >
Carbon dioxide is a colorless and odorless gas at room temperature and pressure. Its chemical properties are relatively stable, and it does not react easily with common substances under normal conditions. However, at high temperature and pressure and with suitable catalysts, it can participate in many reactions, such as reacting with hydrogen to form organic compounds such as methanol. This reaction is of great significance for the recycling of carbon resources. It has a certain solubility in water, and after dissolving, part of it reacts with water to form carbonic acid, making the solution weakly acidic. This property plays a key role in the formation of natural karst landforms.
1,3-azole, with aromatic properties, and the presence of nitrogen and oxygen atoms makes the distribution of cyclic electron clouds uneven. The hydrogen atom on the oxazole ring has a certain acidity, which can leave under the action of a strong base, thereby triggering subsequent reactions such as nucleophilic substitution. Due to its special structure, it can also be used as a ligand to form complexes with metal ions, showing unique properties in the field of catalysis. Due to its ring stability, it can participate in cycloaddition reactions under specific conditions to construct more complex cyclic compounds.

To prepare 2 - [ (4-cyanobenzyl) carbonyl] - 4,5-dihydroxy-1,3-indanedione, the synthesis method is as follows:
First, with suitable starting materials, the basic skeleton is constructed through a multi-step reaction. Usually, aromatic compounds with suitable substituents can be selected by Friedel-Crafts acylation reaction to introduce acyl groups on the aromatic ring. This step requires careful selection of reaction conditions and acylation reagents to ensure the selectivity of the reaction check point.
Then, the cyanobenzyl moiety is introduced. The reagent containing cyanobenzyl group can react with the acylated intermediate through nucleophilic substitution reaction. In this process, the type and amount of reaction solvent and base need to be optimized to improve the reaction efficiency and product purity.
Furthermore, carry out the hydroxylation step. Suitable oxidizing agents or hydroxylating reagents can be selected to introduce hydroxyl groups at specific positions to form a 4,5-dihydroxyl structure. This step requires attention to the regioselectivity and stereochemistry of the reaction to avoid unnecessary side reactions.
After each step of the reaction, fine separation and purification operations, such as column chromatography, recrystallization, etc., are required to obtain high-purity target products. During the synthesis process, factors such as reaction temperature, time and material ratio should be strictly controlled to ensure that the reaction can proceed according to the expected path, so as to efficiently synthesize 2- [ (4-cyanobenzyl) carbonyl] -4,5-dihydroxy-1,3-indanedione.

Looking at your question, I seem to want to know the price range of dioctyl, glutaric acid, carbon dioxide, and mono- and tri-butadiene in the market. However, the price of these items is often different due to changes in time, place, quality and supply and demand, so it is difficult to determine.
Today, according to common sense, the price of dioctyl, or due to raw materials and market supply and demand, ranges from thousands to more than 10,000 per ton. For glutaric acid, the price is also subject to a variety of factors, ranging from tens to more than 100 yuan per kilogram. Carbon dioxide, because of its wide range of uses and easy production, may be relatively cheap, ranging from a few to tens of yuan per cubic meter. Tri-butadiene is an important chemical raw material, and its price is often in the tens of thousands of yuan per ton. However, the market situation is changeable or fluctuates.
Prices of various things are difficult to generalize, depending on the specific market conditions, trading conditions and quality. If you want to get an accurate price, you can get the exact number at the moment when you carefully check the chemical market information and consult industry insiders or merchants.

"Tiangong Kaiwu" is a great scientific and technological work in our country in ancient times. Its style is simple and the narrative is clear. If you answer this question in classical Chinese form, it may be as follows:
"The storage conditions of Fu 2- [ (4-cyanobenzyl) carbonyl] -4,5 -dioxide-1,3 -azoline are also related to the stability and utility of this substance. The properties of this substance may change due to various external factors, so the storage method should be done with caution.
Generally speaking, it should be stored in a cool, dry and well-ventilated place. If it is cool, it can avoid the disturbance of high temperature to prevent the chemical change caused by the heat of the substance and damage its inherent nature. A dry place can prevent moisture erosion, and it can deteriorate due to moisture or reaction with the substance. Well ventilated, it can disperse harmful gases that may be generated and keep the storage environment safe.
Furthermore, it should be kept away from fire and heat sources, both of which can cause a sudden rise in temperature and trigger unpredictable chemical reactions. It also needs to be stored separately from oxidizing agents, acids and other substances. Due to its active chemical nature, contact with them is prone to violent reactions and endangers safety. When the storage place is equipped with suitable materials to contain leaks to prevent accidental leakage, it can be properly disposed of in time to avoid greater troubles. "
