Merck 106044 Dichloromethane for liquid chromatography LiChrosolv®. CAS No.: 75-09-2, chemical formula CH₂Cl₂
Catalogue Number	106044
Synonyms	DCM, Methylene chloride, Methylene dichloride
Description	Dichloromethane
Overview	With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.
