Description
2,2'-Dichlorodiethyl ether (CAS 111-44-4, EC 203-870-1) is a chlorinated ether compound commercially known as Chlorex and also referenced as bis(chloroethyl) ether or dichloroethyl ether. It carries no assigned E-code and is classified under HS code 29091900.
In plastics and polymer processing, it functions as a flame retardant by releasing halogen radicals during combustion, interrupting the oxidation chain reaction. It also serves as a carrier solvent in textile and leather treatments and exhibits antimicrobial activity applied in preservation applications within printing and packaging substrates.
2,2'-Dichlorodiethyl ether is supplied as a technical-grade liquid and falls under REACH regulation, requiring an up-to-date Safety Data Sheet for EU trade. Procurement teams should confirm supplier REACH compliance documentation and substance authorization status prior to ordering, given its classification as a substance of potential regulatory concern.
