2-mercapto-5-methyl-1-3-4-thiadiazole CAS 29490-19-5,2-mercapto-5-methyl-1-3-4-thiadiazole,CAS 29490-19-5
------
2-Mercapto-5-Methyl-1,3,4-Thiadiazole (MMTD) is a heterocyclic organic compound containing both nitrogen and sulfur atoms in a thiadiazole ring. The presence of a thiol (-SH) group enhances its chemical reactivity, particularly in metal coordination and polymer modification. Due to its structural characteristics, MMTD is widely used in corrosion inhibition, metalworking fluids, and polymer stabilization.
