INFO
Dichloromethane, CH2Cl2
Dichloromethane (CH2Cl2), commonly known as methylene chloride, is a volatile, colorless liquid with a slightly sweet aroma. It is widely used as a solvent, especially in the removal of paint and varnish, and in the decaffeination of coffee and tea. Due to its powerful solvent properties, it can dissolve a wide range of organic compounds, making it a versatile option in many industrial applications. However, dichloromethane's potential health effects, including its role as a potential carcinogen, have led to regulations on its use in consumer products in many countries.Other names
