SINOMER® BMES (Bismercaptoethyl sulfide) is a type of organic compound with a special unpleasant odor. It is often used as an intermediate product in the synthesis of other sulfur-containing organic compounds. It is especially suitable for the synthesis of thioethers, thioesters, sulfoxides and sulfones, etc. . At the same time, it is also the basic raw material for preparing thiocarbamate; DMDS is also used as a co-solvent for various cationic dyes and vat dyes of phthalocyanine IF3G; it can also be used as a sizing agent, leveling agent, and absorbent for vat dye printing. Warming agent can increase the color yield and brightness of printed and dyed materials.
