Description General description N-Methyl-1,2-phenylenediamine is an ortho-diamine. In situ generated diazonium cations of N-methyl-1,2-phenylenediamine were used for the electrochemical modification of glassy carbon electrode. Application N-Methyl-1,2-phenylenediamine may be used in the following studies: • One-pot synthesis of 1-methyl-2(hetero)arylbenzimidazoles. • Preparation of 1-methyl-1H-benzimidazole-2(3H)-thione. • Total synthesis of the angiotensin II receptor antagonist, telmisartan. • Preparation of benzimidazoles from ketene dithioacetals. Packaging 5, 25 mL in glass bottle
