Tolyltriazole


Tolyltriazole is a mixture of isomers or congeners that differ from benzotriazole by the addition of one methyl group attached somewhere on the benzene ring. "The term tolyltriazole generally the commercial mixture composed of approximately equal amounts of 4- and 5-methylbenzotriazole, with small quantities of ".

Structure

Synthesis and reactions

Synthesis is much like that of benzotriazole, but starting with methyl-o-phenylenediamine instead of o-phenylenediamine. Isomers of methyl-o-phenylenediamine include 3-methyl-o-phenylenediamine, 4-methyl-o-phenylenediamine, and N-methyl-o-phenylenediamine.

Applications

Tolyltriazole has uses similar to benzotriazole, but has better solubility in some organic solvents.

Corrosion inhibitor

Environmental relevance

Tolyltriazole is a common "polar organic persistent pollutant", often detected at >0.1 μg/L.
