Description
2,4-Dichloroaniline (CAS 554-00-7, EC 209-057-8) is an aromatic amine supplied as a crystalline powder, also referenced under the abbreviation 2,4-DCA and registry identifiers NSC 8756 and AKOS BBS-00003655. No E-code designation applies to this substance.
In polymer and rubber processing, 2,4-DCA functions as a crosslinker and curing agent by reacting with isocyanates or epoxy groups to build network structures that improve mechanical strength. It also serves as an intermediate in the synthesis of azo colorants for textile and leather dyeing, and contributes antimicrobial activity in preservation formulations targeting microbial growth inhibition.
2,4-Dichloroaniline is supplied in technical grade as a crystalline powder and is registered under REACH (EC 209-057-8), requiring an up-to-date Safety Data Sheet for EU procurement. Buyers should confirm supplier REACH compliance documentation and confirm HS code 29214210 for import classification. Packaging formats vary by supplier volume requirements.
