Benzothiazole-2-carboxylic acid

Benzothiazole-2-carboxylic acid is one of the organic compounds. It has unique physical properties. In order to understand this physical property, let me tell you.
Looking at its appearance, benzothiazole-2-carboxylic acid is in a solid state under normal conditions, and the color may be white to light yellow powder. This color sign is one of the important clues to distinguish this substance in laboratory and industrial scenes. And its powder is fine in texture. Under light, there may be shimmering light, which is like a fine sand flood, which can be seen as a physical appearance.
When it comes to the melting point, the melting point of this compound is quite high, about 220-225 ° C. The melting point is the critical temperature at which a substance changes from solid to liquid. The high melting point of benzothiazole-2-carboxylic acid is due to the strong intermolecular force. The intermolecular force is complex and stable, so that the molecules are closely connected. It takes a higher temperature to break this binding and cause the solid to melt into a liquid state. This high melting point characteristic is of great significance in industrial production. For example, in the process of separation and purification, it can be controlled by temperature to distinguish it from other substances with different melting points according to its melting point characteristics.
Solubility is also an important physical property. Benzothiazole-2-carboxylic acid is slightly soluble in water, because water molecules are polar molecules, and in the molecular structure of benzothiazole-2-carboxylic acid, although there are carboxyl groups that can form hydrogen bonds with water, the part of benzothiazole ring is non-polar structure, the overall polarity is weak, and the interaction with water is not good, so it is difficult to dissolve in water. However, it has good solubility in some organic solvents, such as dimethyl sulfoxide (DMSO), N, N-dimethylformamide (DMF). This difference in solubility provides a basis for the selection of suitable solvents in organic synthesis experiments. In order to involve benzothiazole-2-carboxylic acid in the reaction, soluble organic solvents can be selected to create a good reaction environment and promote the smooth progress of the reaction.
In addition, the density of benzothiazole-2-carboxylic acid is also a physical parameter. Although the exact value varies slightly due to measurement conditions, its density is about 1.5-1.6 g/cm ³. Density reflects the mass of a substance per unit volume, which indicates that it is denser than common lightweight substances. During storage and transportation, density factors need to be considered, as it affects the load-bearing of packaging materials and the arrangement of transportation space.
In summary, the physical properties of benzothiazole-2-carboxylic acid, such as white to light yellow powder appearance, high melting point, special solubility, and certain density, are interrelated, and are used in many fields such as organic synthesis and chemical production. This provides a key basis for researchers and producers to control this compound and help them use it rationally in all aspects.

The method of synthesizing benzothiazole-2-carboxylic acid has been known for a long time, and all methods are reasonable.
First, using o-aminothiophenol and glycolic acid or its derivatives as raw materials, under suitable reaction conditions, the two interact. In this process, the amino group of o-aminothiophenol and the carboxyl group of glycolic acid are condensed and reacted to gradually build a benzothiazole ring, and then obtain benzothiazole-2-carboxylic acid. When reacting, pay attention to the choice of temperature and solvent. Too high or too low temperature can cause the reaction to go astray and obtain unwanted things. The nature of the solvent is related to the reaction rate and the purity of the product. Polar solvents may be helpful to the reaction process.
Second, starting from 2-halobenzothiazole. Make 2-halobenzothiazole and metal magnesium into Grignard reagent, and then react with carbon dioxide. Grignard reagent has high activity. In case of carbon dioxide, carboxyl groups can be introduced to obtain the target product. However, when preparing Grignard reagent, the environment must be dry, otherwise water vapor will easily decompose Grignard reagent and cause the reaction to be difficult.
Third, take benzothiazole as the starting material and add carboxyl groups through oxidation. Commonly used oxidizing agents, such as potassium permanganate, etc. However, the oxidation reaction is not easy to control, and it is easy to over-oxidize, which will damage the yield and purity of the product. Therefore, during the reaction, the amount of oxidant and the reaction time need to be precisely controlled.
All synthesis methods have their own advantages and disadvantages. In practical application, the choice should be made carefully according to many factors such as the availability of raw materials, cost, and product purity requirements.

Between the market and the market, the quality of the product is different, and it depends on factors such as supply and demand. If you want to know the quality of benzothiazole-2-carboxylic acid in the market, please tell me.
