Description and Uses

4-Chloro-o-phenylene-diamine is a browncrystalline powder or leaflets from water; Freezing/Meltingpoint =67-70℃; also reported at 76℃

4-Chloro-o-phenylenediamine can be used as an oxidation base for dye preparation, as a chemical intermediate to produce 5-chlorobenzotriazole, as a curing agent for epoxy resins, as a reagent in gas chromatography, and to synthesize experimental pharmaceuticals. It has been used as a chemical intermediate in dye production and was patented as a hair-dye component, but there is no evidence that it is currently used in the United States for these purposes (IARC 1982, HSDB 2009).
