Dichloromethane (DCM, CAS 75-09-2) is a low-boiling-point, highly soluble haloalkane solvent with core characteristics of non-flammability, rapid evaporation, and moderate polarity. It boasts high purity, controllable impurities, and stable properties, making it suitable for both industrial and high-purity production standards. As a major basic chemical raw material, it exhibits strong compliance, meeting national standards, REACH, and maritime dangerous goods transport standards. Its mature production process and uniform quality make it a mainstream green alternative to flammable solvents in industry.
