2-Chloroaniline, identifiable by CAS 95-51-2, functions as a vital aromatic amine intermediate used primarily in the manufacture of azo dyes and agricultural pesticides. Chemically defined as o-Chloroaniline, this clear to amber liquid (which darkens upon air exposure) serves as a diazotization component for the synthesis of solvent yellow dyes and fast color bases. The substance, often referred to as 2-Chlorobenzenamine or OCA in industrial organic chemistry, acts as a precursor for the production of fungicides and pharmaceuticals due to the reactivity of the amino group ortho to the chlorine atom. We facilitate bulk supply of this toxic organic intermediate with competitive factory pricing, capable of meeting customized specifications for purity (99% min) and moisture content, backed by comprehensive MSDS, TDS, COA documentation.

FAQ - Technical & Supply Chain
-
Q:
Is 2-Chloroaniline chemically synonymous with o-Chloroaniline?
A: Yes, 2-Chloroaniline and o-Chloroaniline refer to the same chlorinated aromatic amine identified by CAS 95-51-2, where the amino group is positioned adjacent (ortho) to the chlorine atom on the benzene ring. -
Q:
Is this intermediate suitable for azo dye synthesis?
A: 2-Chloroaniline is typically applied as a diazo component in the coupling reactions used to produce Fast Yellow GC Base and other azo pigments, providing specific colorfastness properties to the final dye.
