O-TOLUIDINE HYDROCHLORIDE Chemical Properties,Usage,Production

Chemical Properties

white crystalline powder

Uses

o-Toluidine and o-toluidine hydrochloride are used primarily as intermediates in the manufacture of more than 90 dyes and pigments (NCI 1979, IARC 1982, 2000). They are used in acid-fast dyestuffs, azo pigments and dyes, triarylmethane dyes, sulfur dyes, and indigo compounds and as a photographic dye. o-Toluidine is also used as an intermediate for synthetic rubber and rubber vulcanizing chemicals, pharmaceuticals, and pesticides and as a curing agent in epoxy resin systems. Other minor uses of o-toluidine and its hydrochloride salt are as an intermediate in organic synthesis and as an ingredient in a clinical laboratory reagent for glucose and hemoglobin analyses.

Uses

o-Toluidine Chloride is a carcinogenic and toxic aromatic amine contained in hair dye, henna and dyed hair samples. Prilocaine USP Related Compound A

General Description

Green crystals or white crystalline solid. Melting point 215-217°F. Highly toxic.
