Overview
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 across multiple industrial sectors.
It functions primarily as a building block in the synthesis of a broad range of downstream chemicals, from agrochemicals to pharmaceutical actives. In pharmaceuticals, it serves as a key alkylating intermediate.
This compound is essential in the production of active pharmaceutical ingredients, including antihistamines and analgesics. Agrochemical manufacturers use it to synthesize herbicides, fungicides, and insecticides where benzyl group introduction is required.
In plastics and polymers, it acts as a polymerization initiator and chain modifier, contributing to the production of quaternary ammonium compounds and ion-exchange resins. This versatility makes it a staple in chemical manufacturing.
The printing and packaging industry applies it in the manufacture of benzyl-based dyes and pigment intermediates used in inks and coatings. It is supplied as a colorless to pale yellow liquid in standard industrial packaging.
Logistics options include drums and ISO tank containers for bulk orders. It is available in technical and high-purity grades, with purity specifications typically ranging from 98% to 99%+ depending on the application.
Pharmaceutical and specialty chemical buyers commonly require certificate of analysis documentation confirming low residual toluene and acid content. Our material meets rigorous industrial and USP or BP standards where applicable.
