1. Bis(hydroxymethyl)sulfide(BMES) is a kind of organic compounds with special unpleasant odor, which is often used as intermediate products in the synthesis of other sulfur-containing organic compounds, especially suitable for the synthesis of sulfur ether, sulfuric acid, suboxo and soar, etc. At the same time, it is also the basic raw material for the preparation of thiocarbamic acid.
2. At the same time, it is also the basic raw material for the preparation of thiocarbamic acid cool; BMES is also used as a co-solvent for the reduction of various cationic dyes of IF3G.
3. It can also be used as mixing agent, leveling agent and temperature absorber for printing with reduced dyes, which can increase the amount of color and vividness of printed and dyed materials.
