What is o-Toluidine?

The Uses of o-Toluidine

A carcinogenic and toxic aromatic amine contained in hair dye, henna and dyed hair samples.
o-Toluidine, is a methemoglobin-inducing chemical and a human carcinogen. Commercial production of o-toluidine was first reported in the United States in 1922. o-Toluidine and its hydrochloride salt are used primarily as intermediates in the manufacture of dyes and pigments for printing textiles, in color photography, and as biologic stains. In addition, o-toluidine is used as an intermediate for rubber vulcanizing chemicals, pharmaceuticals, and pesticides. Other minor uses include intermediate for organic synthesis and clinical laboratory reagent for glucose analysis (IARC, 2000, 2010; Woo and Lai, 2012).
