5-(2-BROMOPHENYL)-1H-TETRAZOLE Usage And Synthesis

Chemical Properties	white to off-white powder
General Description	5-(2-Bromophenyl)-1H-tetrazole is a 5-substituted 1H-tetrazole. It can be synthesized via silica supported sulfuric acid catalyzed [3+2] cycloaddition of nitriles and sodium azide. Copper-catalyzed reaction of 5-(2-bromophenyl)-1H-tetrazole with ethyl 2-cyanoacetate has been reported to afford ethyl 1,3-diaminoisoquinoline-4-carboxylate.
