Specifications Dichloromethane is a chlorinated organic solvent that is susceptible to degradation with time. This can be suppressed by adding amylene as a stabilizer.Synonyms: DCM; Methylene chlorideMolecular Formula: CH2Cl2Molecular Weight: 84.93Linear Structural Formula: CH2Cl2MDL Number: MFCD00000881Purity: >=99.8%Melting Point: -97 C (lit.)Density: 1.325 g/mL at 25 C (lit.)Refractive Index: n20/D 1.424 (lit.)Application: 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.Assay: ≥99.8%Autoignition Temp.: 1223°FBP: 39.8-40°C mmHg(lit.)Contains: 50-150 ppm amylene as stabilizerDensity: 1.325 g/mL at 25°C(lit.)Evapn.
