1939-99-7 - Application:

Benzylsulfonyl Chloride (α-Toluenesulfonyl Chloride) (CAS: 1939-99-7) is mainly used as organic synthetic intermediates and pharmaceutical intermediates. Benzylsulfonyl Chloride is a sulfonating reagent that is frequently used to introduce the mesylate functional group into organic compounds. Among other things, the mesylate functional group is commonly used to improve the reactivity and solubility of organic compounds.
Benzylsulfonyl Chloride is widely used in the synthesis of pharmaceuticals, pesticides, dyes, and other fine chemicals. Benzylsulfonyl Chloride is perfect for mesylation reactions because of its high electrophilicity and low nucleophilicity.
