Oxidation of benzotriazole by potassium dichromate in sulfuric acid was written by Tyupalo, N. F.;Stepanyan, A. A.. And the article was included in Zhurnal Prikladnoi Khimii (Sankt-Peterburg, Russian Federation) in 1980.Safety of 1H-1,2,3-Triazole-4,5-dicarboxylic acid This article mentions the following:
The title reaction with 2.5-3 mol K2Cr2O7/mol benzotriazole gave salt I as the product. The structure of the product was determined by mass spectra. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6Safety of 1H-1,2,3-Triazole-4,5-dicarboxylic acid).
1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) belongs to triazole derivatives. The triazole ring is a relatively stable functional group, and the triazole bond can be used for a variety of applications, such as replacing the phosphate backbone of DNA. 1,2,3-Triazoles are usually prepared following (3+2) cycloaddition protocols. A common technique for unsubstituted triazoles is the Huisgen azide-alkyne 1,3-dipolar cycloaddition: a azide and an alkyne react at high temperature to form a ring. However, the Huisgen strategy produces a mixture of isomers (typically 1,4- and 1,5-disubstituted) when used to produce substituted triazoles.Safety of 1H-1,2,3-Triazole-4,5-dicarboxylic acid
