[C][=C][C][=Branch1][#Branch2][=C][Branch1][=Branch1][C][=C][Ring1][=Branch1][Cl][N][N]"}, {"from": "gpt", "value": "The molecule is 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)"}]
