Tosylchloride CAS 98-59-9

What is of  Tosylchloride with CAS 98-59-9?

Tosyl chloride (TsCl) CAS 98-59-9 is a fine chemical product, which is widely used in dye, medicine and pesticide industries. In the dye industry, it is mainly used to manufacture intermediates for disperse, ice dye and acid dye; in the pharmaceutical industry, it is mainly used to produce sulfonamides, mesotrione, etc.; in the pesticide industry, it is mainly used for mesotrione, sulcotrione, metalaxyl-M, etc. With the continuous development of dye, medicine and pesticide industries, the international demand for this product is increasing, especially in Europe and the United States, and the market prospects are broad.

Đặc điểm kỹ thuật

Ứng dụng

1.Pharmaceutical industry: Tosyl chloride is used to synthesize a variety of drugs, such as intermediates of cephalosporin antibiotics. It can introduce p-toluenesulfonyl groups by reacting with amino acids or other organic compounds, thereby changing the structure and properties of drug molecules and enhancing the stability, activity and bioavailability of drugs.

2.Pesticide industry: Tosyl chloride is an important raw material for synthesizing some pesticides. For example, it can be used to prepare pesticides such as insecticides and fungicides. By reacting with different organic amines or alcohol compounds, it can generate pesticide intermediates with specific biological activity, and then synthesize high-efficiency, low-toxic and environmentally friendly pesticide products.

3.Dye industry: Tosyl chloride plays an important role in dye synthesis. It can be used as a dye intermediate, and its structure can be introduced into the dye molecule through a series of chemical reactions, thereby improving the dyeing performance, color brightness and fastness of the dye. For example, it is used to synthesize certain acid dyes, reactive dyes, etc.

4.Organic synthesis: Tosyl chloride is a commonly used sulfonylating agent in organic synthesis. It can undergo sulfonylation reaction with various compounds such as alcohols and amines to introduce p-toluenesulfonyl groups into organic molecules. This group is often used as a protecting group in organic synthesis or to change the physical and chemical properties of molecules to facilitate subsequent reactions. For example, in peptide synthesis, p-toluenesulfonyl chloride is often used to protect the amino group of amino acids to prevent unnecessary side reactions during the reaction.
