2-Chlorobenzonitrile is a chloro-benzonitrile synthesis intermediate — a building block used in the manufacture of dyes, agrochemicals and pharmaceutical intermediates (it is a precursor to 2-chlorobenzamide, 2-chlorobenzoic acid and related building blocks). Identity: CAS 873-32-5.
What it is
2-Chlorobenzonitrile (CAS 873-32-5, C7H4ClN) is a chloro-benzonitrile sold as a synthesis intermediate — a defined building block that downstream manufacturers convert into finished products. It is one of the most widely used chlorobenzonitriles.
Role in synthesis
As a nitrile, the cyano group can be hydrolyzed to the corresponding acid or amide, or reduced to a primary amine, while the ring halogens are reactive sites for nucleophilic aromatic 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 dyes, agrochemicals and pharmaceutical intermediates (it is a precursor to 2-chlorobenzamide, 2-chlorobenzoic acid and related building blocks). 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-Chlorobenzonitrile 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-chlorobenzonitrile used to make?
2-Chlorobenzonitrile (CAS 873-32-5) is a synthesis intermediate used to make dyes, agrochemicals and pharmaceutical intermediates, including 2-chlorobenzamide and 2-chlorobenzoic acid derivatives.
Can RawSource supply 2-chlorobenzonitrile in bulk or custom quantities?
Yes — RawSource supplies 2-chlorobenzonitrile 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-Chlorobenzonitrile?
2-Chlorobenzonitrile (CAS 873-32-5) 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 212-836-5).
