Use
Bis(chloromethyl)ether (BCME) is used asan intermediate in anion-exchange quater nary resins. Its use as a chloromethylationreagent in industry is being discontinuedbecause of its high carcinogenic properties.Exposure risks associated with this com pound can arise during the use or productionof chloromethyl methyl ether when the lat ter compound comes in contact with tracesof water in the presence of hydrogen orhydroxyl ions. It may occur in trace amountsin chloromethyl methyl ether.
