What are its key applications?

1. ​Industrial Solvent:
   • Removes paint, degreases metals, and processes polymers like ​polyurethane foams

     .
   • Dissolves pharmaceutical compounds (e.g., antibiotics) and aids in drug synthesis
     2
     .
2. ​Chemical Synthesis:
   • Intermediate in producing ​chloroform and other chlorinated chemicals

     .
3. ​Chromatography:
   • Historically used in thin-layer chromatography (TLC) for its high volatility and miscibility with organic solvents

What are the safety and environmental concerns?

• ​Toxicity:
  • Classified as a ​Group 2B carcinogen (possibly carcinogenic to humans) by the International Agency for Research on Cancer (IARC)

    .
  • Prolonged exposure may cause liver/lung damage and central nervous system depression

    .
• ​Environmental Impact:
  • Non-flammable but persistent in the environment. Efforts are underway to replace DCM with greener alternatives like ​bio-derived esters(e.g.,tert-butyl acetate)

How is DCM handled in laboratories and industries?

• ​Protective Measures:
  • Use ​gloves, goggles, and fume hoods to avoid inhalation or skin contact

    .
• ​Storage:
  • Store in sealed containers away from heat sources and oxidizers.
