5-Chloro-2-methylbenzothiazole, which is white to light yellow crystalline powder. Its melting point is between 50 and 52 degrees Celsius. This characteristic makes it gradually melt from solid to liquid at a specific temperature. In many reactions or processes involving temperature changes, the melting point is very critical.
Its boiling point is 275-277 degrees Celsius. When the temperature rises to the boiling point, the substance is converted from liquid to gaseous. In chemical operations such as separation and purification, boiling point is an important parameter.
5-chloro-2-methylbenzothiazole is slightly soluble in water, but soluble in organic solvents such as ethanol, ether, and chloroform. This difference in solubility is of great significance in the process of extraction, separation and preparation of solutions of substances. According to the difference in solubility in different solvents, suitable solvents can be selected for related operations.
Because its molecular structure contains chlorine atoms and benzothiazole rings, it has certain chemical activity. In the field of organic synthesis, it can be used as a key intermediate to participate in many chemical reactions and replace nucleophiles. Chlorine atoms can be replaced by other functional groups to construct more complex organic molecular structures, which are widely used in the synthesis of fine chemicals such as pharmaceuticals and pesticides.

The chemical properties of 5-chloro-2-methylbenzothiazole are quite stable under normal conditions. This compound has a specific structure, and the existence of the benzothiazole ring endows it with a certain conjugate system, which makes the distribution of electron clouds in the molecule relatively uniform. The chlorine atom at the 5-position and the methyl at the 2-position also affect its properties.
The chlorine atom has a certain electron-absorbing property. Although it can reduce the electron cloud density on the benzothiazole ring, due to the existence of the conjugate effect, the stability of the overall structure is not greatly affected. The methyl group is the power supply, which can increase the electron cloud density on the ring to a certain extent, check and balance the interaction with the chlorine atom, and maintain the stability of the molecule to a certain extent.
In common chemical environments, without specific reagents and conditions, 5-chloro-2-methylbenzothiazole is not prone to spontaneous significant chemical reactions. When encountering strong oxidizing agents or reducing agents, due to the stability of the ring system, the reaction conditions need to be relatively harsh to promote the reaction.
However, the stability of chemical substances is not absolute. Under specific high temperatures, high pressures, or the presence of special catalysts, their stability or destruction can lead to the occurrence of chemical reactions. However, such situations are special and not normal. Overall, 5-chloro-2-methylbenzothiazole is chemically stable under general chemical operation and storage conditions.

The synthesis method of 5-chloro-2-methylbenzothiazole, through the ages, many parties have their own wonderful methods. First, the starting materials are o-aminothiophenol and chloroacetyl chloride. Under suitable reaction conditions, the two first go through acylation reaction, and the amino group of o-aminothiophenol is cleverly combined with the acyl chloride group of chloroacetyl chloride to form a key intermediate. Then, the intermediate undergoes an intramolecular cyclization reaction under the action of dehydrating agents such as concentrated sulfuric acid. After a series of electron cloud rearrangements and chemical bond recombination, 5-chloro-2-methylbenzothiazole is finally obtained. The reaction steps of this path are relatively clear and the conditions are easier to control.
Furthermore, 2-amino-6-chlorobenzonitrile and potassium sulfide can also be used as raw materials. In a specific solvent, under certain temperature and pressure conditions, the cyano group and potassium sulfide undergo nucleophilic substitution reaction first, and sulfur atoms are introduced. Then, through suitable cyclization reagents and reaction conditions, intracellular cyclization is induced to construct the core structure of benzothiazole, and then the target product 5-chloro-2-methylbenzothiazole is formed. The raw materials for this route are relatively common, but the precise control of the reaction conditions is required.
In addition, 2-chloro-6-methylaniline is used as the starting material, which reacts with carbon disulfide and alkali. Carbon disulfide first undergoes nucleophilic addition with amino groups to form sulfur-containing intermediates, and then further cyclizes under alkali catalysis. After multi-step conversion, 5-chloro-2-methylbenzothiazole is successfully synthesized. This method cleverly uses the characteristics of carbon disulfide to introduce sulfur atoms, which provides a different idea for synthesis. However, the reaction process is relatively complicated and requires fine operation to obtain a higher yield.

5-Chloro-2-methylbenzothiazole is in the market. What is its price? This is a key substance in the field of fine chemicals. It has a wide range of uses and can be used as a raw material for the synthesis of medicines, pesticides and dyes. Therefore, its price is influenced by many factors.
The first to bear the brunt is the cost of raw materials. The synthesis of 5-chloro-2-methylbenzothiazole requires specific starting materials and reagents. The fluctuation of raw material prices has a great impact on its selling price. If raw materials are scarce or the preparation cost is high, the price of the product will be high.
Furthermore, the production process is also key. Efficient and advanced processes can reduce production costs, improve product quality and output, and make prices more competitive. On the contrary, if the process is complicated, the yield is low, and the cost rises, the price will also rise.
The market supply and demand situation also affects its price. When demand is strong and supply is limited, the price will rise; if the market is saturated and there is excess supply, the price will fall.
In addition, the quality level is also related to the price. High-purity, high-quality products are mostly used in high-end fields, and the price is naturally high; while for general quality products, the price is slightly lower.
In terms of the current market, the price of 5-chloro-2-methylbenzothiazole fluctuates between a few hundred and several thousand yuan per kilogram. However, this is only an approximation, and the actual price will vary due to the above factors. When purchasing or trading, when carefully observing market dynamics and comparing multiple parties, a reasonable price can be obtained.
