What are the physical properties of 6-amino-2-methylbenzothiazole?
6-Amino-2-methylbenzothiazole is one of the organic compounds. Its physical properties are quite unique, let me tell them one by one.
Looking at its appearance, it usually takes the form of white to light yellow crystalline powder. This color state is easy to distinguish with the naked eye, and it is an important feature in practical application and identification.
When talking about the melting point, it is about 116-118 ° C. The characteristics of the melting point are of great significance in the identification of substances and the judgment of purity. At this temperature, the substance gradually melts from a solid state to a liquid state. This transformation process follows specific physical laws and can be used as an important basis for studying its thermodynamic properties.
In terms of solubility, it exhibits a certain solubility in organic solvents. Common organic solvents such as ethanol and acetone can partially dissolve 6-amino-2-methylbenzothiazole. However, in water, its solubility is poor. This difference in solubility determines the dispersion of the substance and the way it participates in the reaction in different chemical systems and reaction environments.
Furthermore, this substance has a certain stability. However, it should be noted that it should be avoided from contact with strong oxidants, strong acids, strong bases and other substances. Because of encountering it, it may trigger a chemical reaction, destroy its molecular structure, and cause the original properties to change.
The properties of its density and vapor pressure also affect its behavior in different environments. Although the exact value of its density is related and needs to be accurately determined by professional instruments, the approximate range can help to understand its distribution in the mixture. Although the vapor pressure is low, under specific temperature and pressure conditions, it will also affect the proportion of the substance in the gas phase.
In summary, the physical properties of 6-amino-2-methylbenzothiazole, from the aspects of appearance, melting point, solubility, stability, etc., together outline its unique physicochemical profile, which lays an important foundation for its application in many fields such as chemical industry and medicine.
What is the chemical synthesis method of 6-amino-2-methylbenzothiazole?
The synthesis of 6-amino-2-methylbenzothiazole has been known for a long time. The method is complicated, but there are also traces to follow.
To obtain this compound, one of the common methods is to use 2-methylbenzothiazole as the starting material. First, carefully handle 2-methylbenzothiazole with appropriate nitrifying reagents, such as a mixture of concentrated nitric acid and concentrated sulfuric acid. This step requires careful temperature control to prevent side reactions from occurring. Generally speaking, the reaction system is placed in a low temperature environment, such as between 0 ° C and 5 ° C, and the nitrifying reagent is slowly added dropwise to selectively introduce nitro into specific positions of the benzothiazole ring to obtain nitro-substituted 2-methylbenzothiazole derivatives.
Subsequently, the nitro group needs to be reduced to an amino group. The reduction is often carried out by a combination of reducing agents such as iron powder and hydrochloric acid, or hydrogen under the action of a suitable catalyst (such as palladium carbon). Taking iron powder and hydrochloric acid as an example, the nitro compound is placed in a hydrochloric acid solution containing iron powder and heated to reflux. The iron powder gradually dissolves in an acidic environment, releasing new hydrogen, which can gradually reduce the nitro group to an amino group to obtain 6-amino-2-methylbenzothiazole.
There is another method, using anthranilic acid and carbon disulfide as raw materials. Under alkaline conditions, the condensation reaction of the two occurs first. Sodium hydroxide or potassium hydroxide can be used as a base, and the reaction temperature is controlled in an appropriate range, such as between 60 ° C and 80 ° C. After condensation, a sulfur-containing intermediate product is formed. Then methylation reagents, such as iodomethane or dimethyl sulfate, are carried out under the catalysis of suitable solvents and bases, and finally the target product 6-amino-2-methylbenzothiazole can be obtained.
This method has advantages and disadvantages. The synthesis needs to be carefully selected according to many factors such as the availability of raw materials, the ease of control of reaction conditions, and the purity requirements of the product.
What is the price range of 6-amino-2-methylbenzothiazole in the market?
The price of 6-amino-2-methylbenzothiazole in the market is difficult to determine. This is due to the complex market conditions, and the price varies with many reasons.
In the past, the price of the market often varied according to the supply and demand situation, the difficulty of the production method, the amount of raw materials and the quality. If there are many people in need, the supply is limited, and the price must rise; on the contrary, if the supply exceeds the demand, the price will fall.
The simplicity of the production method is also related to its price. If the production requires exquisite technology and high-priced materials, the cost will be high and the price will be high; if the production method is simple, the cost will be low, and the price will be close to the people.
The amount of raw materials is related to the price. The raw materials are widely available, and the price is stable and cheap; if the raw materials are rare, the price will increase.
The quality is also the key to the price. Those with high quality, the price is high; those with average quality, the price is low.
According to past market estimates, the price may be between tens of yuan and hundreds of yuan per kilogram. However, this is only speculation, not certainty. To know the real-time price, you should consult the chemical raw material supplier, the broker in the market or the platform that carefully observes the price of chemical products to get an accurate price.
