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 (CAS 29385-43-1) 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 (not involved here).
Applications
Tolyltriazole has uses similar to benzotriazole, but has better solubility in some organic solvents.
Corrosion inhibitor
