Empirical Formula (Hill Notation): CH2Cl2, Molecular Weight: 84.93, anhydrous, ≥99.8%, contains 40-150 ppm amylene as stabilizer, Synonym: DCM, Methylene chloride. Dichloromethane may be used as a solvent for the oxidation of primary and secondary alcohols using dipyridine-chromium(VI) oxide. Lithium perchlorate suspended in DCM is an effective medium for Mukaiyama aldol reactions of aldehydes with silyl ketene acetal. DCM may also be used as solvent for the synthesis of 2-bromo-6-lithiopyridine from 2,6-dibromopyridine via lithium-bromine exchange reaction.
