2-Tolidine is slightly soluble in water (1.3 g/L) and has a melting point of 129 °C. It readily forms salts with acids, such as the hydrochloride which is commercially available. 2-Tolidine can be produced by a benzidine rearrangement from a hydrazine derivative.
2-Tolidine is a commercially important aromatic amine used mainly for dye production, but also for the production of certain elastomers. 2-Tolidine is an intermediate for the production of soluble azo dyes and insoluble pigments used particularly in the textile, leather and paper industries.
2-Tolidine also widely used as a reagent or indicator in analytical, clinical and forensic chemistry, such as in the analytical determination of gold.
2-Tolidine is toxic and possibly carcinogenic. It is listed as an IARC Group 2B carcinogen, meaning it is "possibly carcinogenic to humans".
