Methyleenchloride

"Methyleenchloride" is not a standard chemical name in modern nomenclature and does not appear as a distinct entry in major chemical registries. The term is likely a misspelling, an archaic or vernacular variant, or a translation of more common names for simple chlorinated methane compounds. Context (literature, language, or product labeling) determines the intended substance.

Two frequently confused candidates are methylene chloride (dichloromethane, DCM; CH2Cl2) and methyl chloride (chloromethane; CH3Cl). Methylene chloride is a colorless, volatile liquid widely used as an industrial solvent, paint stripper and extraction solvent; it is nonflammable but poses health risks including central nervous system effects and suspected carcinogenicity with chronic exposure. Chloromethane is a flammable gas used as a feedstock in silicone and other chemical manufacture and occurs naturally in the environment; it has toxic and asphyxiant properties at elevated concentrations.

Because similar-sounding names can refer to very different chemicals with distinct hazards, users encountering "methyleenchloride" should verify the intended compound by checking CAS numbers, chemical formulas, or material safety data sheets (MSDS/SDS). Regulatory classifications, workplace exposure limits, and handling precautions vary among chlorinated methanes, so consult authoritative safety and regulatory sources for accurate identification and guidance.
