Description
2-Chlorobenzaldehyde (CAS 89-98-5, EC 201-956-3, formula C7H5ClO) is an aromatic aldehyde commercially known by the abbreviations OCAD and O-Chlorobenzaldehyde, with regional trade names including 2-Chlorbenzaldehyd and 2-Clorobenzaldeide. It carries no assigned E-code. No E-code applies to this substance.
In pharmaceutical synthesis, 2-Chlorobenzaldehyde serves as a key intermediate in the production of active ingredients, where its reactive aldehyde group undergoes condensation reactions to build complex molecular structures. In textile and leather processing, it functions as an antimicrobial agent by disrupting microbial cell membranes. It also acts as a monomer in polymer chemistry, initiating chain-forming reactions in specialty resin production.
This material is supplied as a technical-grade liquid compliant with REACH registration requirements and is classified under HS code 29130000. Procurement quantities typically range from drum to IBC formats. Buyers should confirm purity specifications and SDS documentation prior to order placement.
