Triethylene glycol monochlorohydrin

Triethylene glycol monochlorohydrin (CAS 5197-62-6, EC 225-984-0) is a chlorinated glycol ether supplied as a colourless liquid under the abbreviations CEEE and NSC 2636, and the common names 8-Chloro-3,6-dioxaoctanol and 8-Chloro-3,6-dioxa-1-octanol. It carries no assigned E-code and is classified under HS code 29094990.

In polymer and plastics manufacturing, the compound acts as a reactive solvent and polymerization initiator, where its terminal chlorine group participates directly in chain-initiation reactions. In pharmaceutical synthesis and agrochemical production, it functions as a carrier solvent, facilitating the controlled delivery of active intermediates during multi-step reaction sequences.

This material is available in standard industrial grades and supplied in compliance with REACH registration requirements applicable to the European market.
