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 [refers to] the commercial mixture composed of approximately equal amounts of 4- and 5-methylbenzotriazole, with small quantities of [their respective 7- and 6-methyl tautomers]".[1]
