Application

Chloromethyl methyl ether (MOM-Cl) can be used as a reagent:
  •  For the introduction of the methoxymethyl (MOM) protecting group by converting alcohols to methoxy methyl (MOM) ethers.
  •  To prepare some methoxymethyl group containing metal complexes coordinated to carbonyl and dipyridyl ligands.        
  • In the preparation of fluorene/chloromethyl methyl ether cross-linked polymers by Friedel-Crafts polymerization.
