What is Tosyl chloride?

• With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Tosyl chloride   which has developed particularly rapidly in recent years. Do you know about Tosyl chloride?
• The official answer：White flaky crystals. Melting point 71℃. Boiling point 151.6℃ (1.67kPa), 145-146℃ (2.0kPa). Freely soluble in alcohol, ether, and benzene, insoluble in water. As a fine chemical product, p-toluenesulfonyl chloride (HCl) is widely used in the dyestuff, pharmaceutical, and pesticide industries. In the dyestuff industry, it is mainly used as an intermediate in the manufacture of dispersing, ice dye, and acid dyes; in the pharmaceutical industry, it is mainly used in the production of sulfonamides, metsulfuron, etc.; in the pesticide industry, it is mainly used in metsulfuron, sulforaphane, semicarbazone, etc. With the continuous development of the dyestuff, pharmaceutical, and pesticide industries, the demand for the product is growing internationally, especially in Europe and America, with a broad market prospect.

What’s the application of Tosyl chloride?

• HCl is a white crystalline flake with a melting point of 69-71°C. It is an important intermediate of organic synthesis, mainly used in the synthesis of aminosulfonyl chloramphenicol, chloramphenicol-T, methylsulfonyl molds, and other drugs. It is an intermediate of dispersed dyes, ice dyes, and acid dyes. It is also used in the production of methanesulfuron. Used as analytical reagent, also used in organic synthesis, dye preparation, and hormone synthesis in molecular rearrangement reaction for organic synthesis, sulfonamide drugs and pesticide intermediates organic synthesis, dyestuff, determination of primary and secondary amines, phenols.
