Description
2-Chloroaniline (CAS 95-51-2, EC 202-426-4) is an aromatic amine supplied under the abbreviations OCA and o-Chloroaniline, with no assigned E-code. It belongs to the chlorinated aniline family and is handled as a liquid intermediate in industrial synthesis workflows.
In textile and leather dyeing, 2-Chloroaniline serves as a diazonium precursor, coupling with other compounds to form azo colorants with strong substrate affinity. In polymer and plastics manufacturing, it functions as a crosslinker and curing agent, reacting with epoxy or isocyanate systems to build network structures that improve thermal and mechanical resistance.
This material is registered under REACH and subject to standard industrial chemical handling requirements. It is available in technical grade suitable for formulation and synthesis applications, supplied in drums and IBC containers. Buyers should confirm current SDS documentation and import classification under HS code 29214210 prior to procurement.
