A synthetic, beige to grey-brown crystalline powder that is slightly soluble in water, soluble in benzene and petroleum ether, and very soluble in ethanol and diethyl ether. It is used as an oxidative base, a chemical intermediate to produce 5-chlorobenzotriazole (an isomer which is a photographic chemical), a curing agent for epoxy resins and a reagent in gas chromatography. The primary routes of potential human exposure to 4-chloro-o-phenylenediamine are ingestion, inhalation, and dermal contact during its production. It is reasonably anticipated to be a human carcinogen. (NCI05)
