Description and Uses
m-Toluidine is an aromatic amine compound widely used as a dye raw material, but the aromatic amines of m-Toluidine and o-anisidine have shown damage to the bladder mucosa and potential carcinogenicity[2]. In addition, m-Toluidine monomers can be synthesized into poly(o-toluidine) by chemical oxidation polymerization in acidic medium, which has anti-corrosion properties for low-carbon steel in 3.5% NaCl[3]. Aniline-m-Toluidine copolymers can also be used to prepare NiO-based multicolor electrochromic films, and the composite films can achieve multiple color changes such as yellow, green, blue and dark brown[4].
m-Toluidine is an intermediate in the manu facture of dyes and other chemicals.
