Thioanisole is used as an intermediate in the preparation of dyes, pharmaceuticals and agrochemicals. It is also used to prepare stable sulfonium salts, sulfoxides and sufones. It is utilized for the cleavage of methyl ethers in association with triflic acid. It acts as a flavoring agent or an adjuvant. It is an important starting material for the synthesis of 3-substituted benzo[b]thiophenes.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
Thioanisole is used as an intermediate in the preparation of dyes, pharmaceuticals and agrochemicals. It is also used to prepare stable sulfonium salts, sulfoxides and sufones. It is utilized for the cleavage of methyl ethers in association with triflic acid. It acts as a flavoring agent or an adjuvant. It is an important starting material for the synthesis of 3-substituted benzo[b]thiophenes.
