Uses

o-Tolidine (CAS NO.119-93-7) is a commercially important aromatic amines used mainly for dye production, but also for the production of certain elastomers. It is also widely used as a reagent or indicator in analytical, clinical and forensic chemistry, such as in the analytical determination of gold. o-Tolidine is used as an intermediate for the production of soluble azo dyes and insoluble pigments used particularly in the textile, leather and paper industries.

It is insoluble in water. o-Tolidine is sensitive to exposure to light. It may be also sensitive to prolonged exposure to air. It is a weak base that forms salts with hydrochloric acid or sulfuric acid. o-Tolidine can be acetylated. It is incompatible with strong agents. Flash point data for o-Tolidine are not available; however, it is probably combustible.
