About Sulfotep

Listed under CAS 3689-24-5, Sulfotep is an analytical reagent available from Vaqora Chemicals. Its molecular formula is C8H20O5P2S2 and its molecular weight is 322.3 g/mol. Its systematic (IUPAC) name is diethoxyphosphinothioyloxy-diethoxy-sulfanylidene-lambda5-phosphane. Alternative names: Dithione and Ethyl thiopyrophosphate.

Store sealed in a dry, well-ventilated location away from incompatible materials. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for agrochemical formulations and laboratory analysis. Buyers come mainly from academic and industrial research and agrochemical production.

Standard pack sizes are 100 mg, 250 mg, 1 g and 5 g, and every batch ships with a Certificate of Analysis (COA) and we export worldwide. A Safety Data Sheet (SDS) and technical specifications are available on request.
