p-Toluenesulfonyl chloride, 98%, Thermo Scientific Chemicals

Description

p-Toluenesulfonyl chloride is used as a precursor in the production of dyes and saccharin. It acts as a dehydrating agent in the conversion of urea to carbodiimide and converts alcohols into the corresponding toluenesulfonate esters. It is also employed as a flow-promoting agent for paints, an adhesive, nitrocellulose, coating material and as a plasticizer for polyamides. Furthermore, it serves as an antistatic agent, as a gloss enhancer in plastic film preparations and as a basic material of electroplating solutions.

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.
