Description
4-Chloroaniline (CAS 106-47-8, EC 203-401-0), also known as p-Chloroaniline or para-Chloroaniline, is an aromatic amine with the molecular formula C6H6ClN. It carries no assigned E-code and is catalogued under HS code 29214210 for customs classification purposes.
In textile and leather processing, 4-Chloroaniline acts as an intermediate in azo dye synthesis, where the amino group undergoes diazotization to couple with dye components and fix color onto fiber substrates. In polymer and rubber manufacturing, it functions as a crosslinker and curing agent, reacting with epoxy or isocyanate systems to build network structures that improve mechanical and thermal resistance.
This material is supplied as a crystalline solid and is subject to REACH registration requirements within the EU. Procurement teams should verify current SVHC status and request a compliant Safety Data Sheet prior to ordering. Standard packaging formats and available grades can be confirmed directly with our technical sales team.
