What is Benzyl chloride?
Benzyl chloride (CAS 100-44-7), also known as omega-chlorotoluene, is a reactive chlorinated aromatic compound used as a chemical intermediate and alkylating agent.
Where is Benzyl chloride used?
- Pharmaceuticals: alkylating intermediate in the production of active pharmaceutical ingredients, including antihistamines and analgesics
- Agrochemicals: synthesis of herbicides, fungicides and insecticides requiring benzyl group introduction
- Plastics and polymers: polymerization initiator and chain modifier for quaternary ammonium compounds and ion-exchange resins
- Printing and packaging: manufacture of benzyl-based dyes and pigment intermediates for inks and coatings
- It serves as a building block in the synthesis of downstream chemicals.
Good to know: Pharmaceutical and specialty chemical buyers commonly require certificate of analysis documentation confirming low residual toluene and acid content.
Commercial specifications
- Purity specifications typically ranging from 98% to 99%+ depending on the application
- Technical and high-purity grades
- Meets industrial and USP or BP standards where applicable
- Drums and ISO tank containers for bulk orders
