Bismuththiol Usage And Synthesis

Description

Dimercapto-1,3,4-thiadiazole (DMTD) is a low-molecular- weight aromatic compound used in the production of cop per corrosion inhibitors for engine oils, flame retardants and photographic development chemicals. Seven cases of industrial allergic sensitization were reported in a manufacturing plant.

Chemical Properties

white to light yellow crystal powde

Uses

Pharmaceutical intermediates; metallic passivator;antioxidant

Uses

2,5-Dimercapto-1,3,4-thiadiazole is used in synthesizing polymers and heavy metal and basic salts. It acts as an additive in lubricating oils, greases and in electrode compositions. It also acts as an intermediate for pharmaceuticals and dyes, as a chelating agent in the analysis of metals. It also serves as an anticorrosion and antirust agent.
