2-Chloroaniline is a chloro-aniline synthesis intermediate — a building block used in the manufacture of azo dyes and pigments, agrochemicals and pharmaceutical intermediates. Identity: CAS 95-51-2.
What it is
2-Chloroaniline (CAS 95-51-2, C6H6ClN) is a chloro-aniline sold as a synthesis intermediate — a defined building block that downstream manufacturers convert into finished products. It is a large-volume dye and pigment intermediate.
Role in synthesis
As an aromatic amine, it can be diazotized and coupled, acylated, or condensed, while the ring substituents tune reactivity and direct further substitution. The substitution pattern (isomer) is part of the identity — confirm the CAS to be sure the isomer matches your route, because position isomers react differently and lead to different products.
What it is used to make
It is a building block toward azo dyes and pigments, agrochemicals and pharmaceutical intermediates. RawSource supplies the intermediate; the downstream synthesis, product registration and any application or efficacy are the responsibility of the manufacturer that uses it.
Forms, grades and handling
Supplied to a defined assay with a Certificate of Analysis (CoA) per lot; define the assay and key impurity limits your route needs. Several halo-aromatic intermediates are hazardous and some are regulated — confirm regulatory status and handling for your jurisdiction, and always consult the current Safety Data Sheet (SDS). Typical values are not a guaranteed specification; the CoA governs.
Bulk and custom-quantity supply
RawSource sources 2-Chloroaniline direct from producers in bulk and custom quantities, with CoA, TDS and SDS per lot. Tell us the assay and impurity limits and your sample/pilot/production quantity, and we will quote it and confirm supply continuity. See the full range in the intermediates guide.

Frequently Asked Questions
What is 2-chloroaniline used for?
2-Chloroaniline (CAS 95-51-2) is an aromatic amine intermediate used to make azo dyes and pigments, agrochemicals and pharmaceutical building blocks (via diazotization and coupling).
Can RawSource supply 2-chloroaniline in bulk or custom quantities?
Yes — RawSource supplies 2-chloroaniline in bulk and custom (sample/pilot/production) quantities with CoA, TDS and SDS per lot. Tell us the assay, impurity limits and quantity, and we will quote it and confirm supply.
What is the REACH and TSCA regulatory status of 2-Chloroaniline (OCA)?
2-Chloroaniline (OCA) (CAS 95-51-2) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 202-426-4).
