CAS 75-09-2 Dichloromethane (DCM) also known as methylene chloride, is a moderately polar (or weakly polar) aprotic solvent. It is used for separating polar organic compounds, including alkaloids, and in liquid-liquid extractions.
Dichloromethane solvent should be stored in a sealed container in a cool, dry, well-ventilated place, away from direct sunlight, heat sources, and ignition sources.
Understanding the Potential Hazards of Dichloromethane CAS No 75-09-2
Classified as a neurotoxin, dichloromethane has been proven to cause damage to the brain and central nervous system (CNS). The Environmental Protection Agency (EPA) has classified it as a probable human carcinogen since high levels of exposure to the chemical has been proven to cause liver and lung cancer in animals.
How to store dichloromethane solvent safely? CAS No 75-09-2
CAS No 75-09-2 dichloromethane solvent should be stored in a tightly sealed container, in a cool, dry, and well-ventilated area, away from direct sunlight, heat, and ignition sources.
| Storage Aspect | Recommendation | Notes |
|---|---|---|
| Temperature | Store below 30°C (86°F) | Avoid heat and sunlight |
| Ventilation | Well-ventilated area | Prevents vapor buildup |
| Container Type | Tightly sealed chemical-resistant containers (HDPE or metal drums) | Avoid plastic that can degrade |
| Segregation | Keep away from strong oxidizers, acids, and bases | Prevents chemical reactions |
| Secondary Containment | Use spill trays or bunding | Controls accidental leaks |
| Labeling | Clearly mark CAS number, hazard class | Helps compliance and emergency response |
| Quantity | Limit bulk storage in one area | Reduces risk in case of accident |
| Fire Safety | Keep away from open flames, sparks, and high-temperature surfaces | Even though DCM is not highly flammable, decomposition gases are toxic |
| Monitoring | Regularly check for leaks and container integrity | Maintains safe storage conditions |
