Description
Benzyl chloride (CAS 100-44-7, EC 202-853-6, C7H7Cl) is an organochlorine compound also known as alpha-chlorotoluene and tolyl chloride. It carries no assigned E-code. The compound is classified as a pharmaceutical intermediate and falls under HS code 29039900.
In pharmaceutical manufacturing, benzyl chloride serves as a benzylation agent, introducing the benzyl group into active ingredient structures through nucleophilic substitution reactions. It also functions as a polymerization initiator in polymer production and is used in agrochemical synthesis to construct pesticidal intermediates via controlled alkylation chemistry.
Benzyl chloride is supplied as a liquid-phase product and is subject to REACH registration requirements within the European Union. Procurement teams should confirm grade specification and purity certificates prior to ordering, as handling classifications require documented safety compliance. Standard industrial packaging formats apply; contact your supplier for available lot sizes.
