Dichloromethane and its Impurities

Dichloromethane volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes. In the food industry, it has been used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavorings. Its volatility has led to its use as an aerosol spray propellant and as a blowing agent for polyurethane foams. Reference standards of Dichloromethane API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
