3-methyl-1H-1,2,4-triazole-5-thiol Chemical Properties,Uses,Production

Description

3-Methyl-1H-1,2,4-triazole-5-thiol is a coagulant agent that has been shown to be effective in the field of wastewater treatment. 3-Methyl-1H-1,2,4-triazole-5-thiol binds metal ions and prevents them from catalyzing reactions in the filtrate. It also has an inhibitory effect on polymerization reactions by binding to functional groups. 3MTH is used as a coagulant additive in many industries, such as papermaking, textile printing and dyeing, food processing and leather tanning. The use of 3MTH has been shown to reduce the amount of water needed during the production process. This product can also be used for coatings and other applications where it is necessary to prevent corrosion or environmental pollution by metal ions.

Chemical Properties

Exists a variety of reciprocal isomers, crystalline (water), melting point 282-283 ° C (270 ° C). It is an intermediate for the production of triazole nucleoside.

Uses

3-Methyl-1H(4H)-1,2,4-triazole-5-thione can be used as a suitable ionophore for fabrication of a new gadolinium(III) ion selective potentiometric sensor. Also used as potential metallo-β-lactamase inhibitors.
