Benzoyl chloride

Benzoyl chloride (CAS 98-88-4) is a high-reactivity acylating agent used in pharmaceutical synthesis, agrochemical manufacturing, and specialty chemical production.

Where is Benzoyl chloride used?

• Pharmaceutical manufacturing: key intermediate in the synthesis of active ingredients, including analgesics, antimicrobials, and UV-absorbing compounds used in topical formulations
• Cosmetics: production of benzoate esters and benzoyl peroxide precursors
• Dyes, resins, and agrochemical intermediates: controlled benzoylation for specific chemical reactions
• Laboratory and biotech: derivatizing agent for analytical workflows, enabling detection and characterization of alcohols and amines
• It introduces the benzoyl group into target molecules, enabling the construction of esters, amides, and anhydrides at industrial scale.

Good to know: Buyers sourcing for pharmaceutical applications should confirm compliance with relevant pharmacopoeial or GMP documentation requirements for their supply chain.

Commercial specifications

• Purity specifications typically range from 98% to 99% or higher depending on the specific grade required.
• Standard quality benchmarks often include USP, BP, or EP standards depending on the region of use.
