Useful:

• Chemical Classes: Solvents -> Chlorofluorocarbons
• Canonical SMILES: CC(F)(Cl)Cl
• Inhalation Risk: On loss of containment this substance can cause serious risk of suffocation when in confined areas.
• Effects of Short Term Exposure: The substance is mildly irritating to the eyes. The substance may cause effects on the central nervous system and cardiovascular system. This may result in lowering of consciousness and cardiac disorders. Suffocation.
• Uses: HCFC 141b has been developed as a substitute for the fully halogenated chlorofluorocarbons, mainly for use as a blowing agent for polyurethane and polyisocyanate insulating foams and as a solvent in electronic and other precision cleaning applications. It is viewed as an interim compound, and production will be phased out beginning in 2003.
