About Phenylmethanesulphonyl fluoride, 99%

Phenylmethanesulphonyl fluoride (CAS 329-98-6) is an enzyme / protein reagent offered by Vaqora Chemicals (Extra Pure grade) at a purity of 99%. With the molecular formula C7H7FO2S, it has a molar mass of 174.19 g/mol. Systematically, it is named phenylmethanesulfonyl fluoride. Common synonyms include a-Toluenesulfonyl fluoride and Benzylsulfonyl fluoride.

It is supplied as a white to off-white to faint yellow powder or crystalline powder. Literature values give a melting point of 92-94 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span enzymatic assays, enzyme inhibition studies and protein research. Buyers come mainly from academic and industrial research and diagnostics and biotechnology.

Standard pack sizes are 1 g, 5 g, 25 g and 1 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
