Are MDC and DCM the same?
Yes, MDC (Methylene Dichloride) and DCM (Dichloromethane) are the exact same chemical compound,with CAS No:75-09-2. Methylene chloride chemical (MDC) is a clear, colorless liquid with a slightly sweet scent that is primarily used as an industrial solvent and as a potent paint stripper and paint thinner.
| CAS Reg. No. | 75-09-2 |
| Empirical formula | CH2Cl2 |
| Molar mass | 84.93 g/mol |
| Appearance | Colorless liquid |
| Boiling point | 40 ºC |
| Water solubility | 13 g/L |
Dichloromethane (DCM) is commonly produced by chlorinating methane. The process also produces the other three C1 chlorohydrocarbons-chloromethane, trichloromethane (chloroform), and tetrachloromethane (carbon tetrachloride). The four are separated via distillation.
What is mDC/DCM (CAS 75-09-2) used for?
MDC and DCM are the same chemical, therefore their uses are also the same. Methylene chloride (dichloromethane, DCM) is a versatile industrial and laboratory solvent primarily valued for its powerful dissolving ability, low boiling point (39.6°C), and non-flammability:
- Industrial Solvent: Paint stripping, adhesive removal, metal cleaning, degreasing, aerosols.
- Chemical Manufacturing: Pharmaceutical production, synthetic fibres, polycarbonate resins, hydrofluorocarbon (HFC) refrigerants.,
- Food & Beverage Industry: Decaffeinating coffee, extracting hops and spices, but safer methods now common.
- Laboratory Use: Extractions and chromatography, organic compounds.
