| | 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. | | Flammability and Explosibility | Notclassified | | Contact allergens | This low-molecular-weight aromatic compound is used
in the production of copper corrosion inhibitors for
engine oils, fame retardants, and photographic devel-
opment chemicals. Seven cases of industrial allergic
sensitization were reported in a manufacturing plant. |
