2-Amino-4,5,6,7-tetrahydro-4-benzothiazole carboxylic acid ethyl ester, is a kind of organic compound. Its physical properties are described in detail as follows:
- ** Properties **: This compound is mostly white to light yellow crystalline powder under normal conditions, with fine texture. Looking at its appearance, the pure one has uniform color and luster, and there is no obvious variegation and foreign matter.
- ** Melting point **: The melting point is in a specific temperature range, about 130 ° C - 135 ° C. When the temperature rises to this range, the compound gradually melts from solid to liquid state, which is of great significance for its identification and purity detection. < Br > - ** Solubility **: In organic solvents, it exhibits different solubility characteristics. In common organic solvents such as methanol, ethanol, and dichloromethane, it has a certain solubility. Among them, it can be better dissolved in methanol and is in a uniformly dispersed solution state; in water, the solubility is relatively low, because the polarity of the molecular structure and the matching of water molecules are not good, only slightly soluble.
- ** Density **: The density is about 1.25 - 1.35 g/cm ³, indicating its unit volume mass, which is an important consideration when it comes to the measurement, storage, and construction of related reaction systems of compounds. < Br > - ** Stability **: Under normal temperature and pressure and dry environment, the compound has good stability and can be stored for a long time without significant deterioration. However, in extreme chemical environments such as strong oxidizing agents, strong acids or strong bases, its structure is easily damaged, and chemical reactions cause structural and property changes.

In order to prepare 2-amino-4,5,6,7-tetrahydrobenzothiazole-4-carboxylic acid ethyl ester, the following ancient method can be used.
The first is the selection and preparation of raw materials. Suitable starting materials need to be found, such as compounds containing nitrogen, sulfur and suitable carbon chain structures. Aniline derivatives and sulfur-containing carbonyl compounds with appropriate substituents can be commonly used, and their purity and quality need to be guaranteed to facilitate the smooth subsequent reaction.
The second is the key reaction step. Place the selected raw materials in a suitable reaction vessel in a certain proportion and carefully. Generally, an appropriate amount of catalyst, such as acid or base catalyst, can be added to organic solvents, such as ethanol, dichloromethane, etc., to promote the efficient progress of the reaction. This reaction may involve the process of cyclization and esterification. During cyclization, the raw material molecules interact and form the core structure of benzothiazole through the cleavage and formation of chemical bonds; in the esterification step, the carboxylic acid part and ethanol catalyze to form the ethyl ester structure of the target product. During the reaction process, factors such as temperature, reaction time and stirring rate need to be carefully regulated. If the temperature is too high, or side reactions occur frequently, the product is impure; if the temperature is too low, the reaction will be slow and take a long time. It can be gradually heated to a suitable reaction temperature, kept stable, and stirred continuously, so that the reactants can be fully contacted and the reaction can be accelerated.
The other is the separation and purification of the product. After the reaction is completed, the system may contain the target product, unreacted raw materials, by-products and solvents. First, most of the organic solvents are removed by distillation, and then further purified by recrystallization and column chromatography. During recrystallization, it is essential to choose the right solvent, so that the target product is dissolved in the hot solvent, and the crystallization precipitates after cooling, while the impurities remain in the mother liquor. Column chromatography achieves separation according to the difference in the partition coefficient between the product and the impurities between the stationary phase and the mobile phase. Pure 2-amino-4,5,6,7-tetrahydrobenzothiazole-4-carboxylic acid ethyl ester can be obtained by these steps.

4-Benzothiazole carboxylic acid, 2-amino-4,5,6,7-tetrahydro-, ethyl ester The price range of this product in the market is difficult to determine. Although "Tiangong Kaiwu" describes many things in detail, this compound is extremely niche and may not be covered in the book.
In today's world, the price of chemicals is influenced by many factors. One is purity. The higher the purity, the more expensive the price. If the purity of this ethyl ester reaches a high level, it is for scientific research purposes, and it is used for precise experiments, its price will be high. The second is related to market supply and demand. If the demand for this product in the scientific research field surges at a certain time and the supply is limited, the price will also rise; on the contrary, if the supply exceeds the demand, the price will decline. Third, the complexity of the production process also has an impact. If the synthesis of this ethyl ester requires cumbersome steps, special raw materials or harsh conditions, the cost will increase and the price will be higher.
In addition, different suppliers have different pricing strategies. The brand effect of large companies, quality control and after-sales improvement, and the price may be higher than that of small factories. And the differences in sales regions, transportation costs, etc., can make the price fluctuate.
From the perspective of the market of common scientific research chemicals, such niche compounds, if the purity is ordinary, the price per gram may be in the tens of yuan to 100 yuan; if the high purity is used for high-end research, the price per gram may reach hundreds of yuan or even higher. However, this is only a rough guess. The actual price needs to be consulted by each chemical reagent supplier.
