Dichloromethane (DCM) is a common low-boiling organic solvent with strong dissolving power for various resins, oils, and coatings. It has a low boiling point, is highly volatile, and features relatively low toxicity compared to other chlorinated hydrocarbons. It is widely used in paint solvents, pharmaceutical intermediates, metal degreasing, electronic cleaning, and polyurethane blowing agents.
