CAS 67-66-3: Chloroform

Description: Chloroform, with the CAS number 67-66-3, is a colorless, volatile liquid with a sweet odor that is non-flammable and has a density greater than water. It is a halogenated hydrocarbon, specifically a trihalomethane, composed of one carbon atom, one hydrogen atom, and three chlorine atoms (CHCl₃). Chloroform is soluble in organic solvents such as alcohol and ether but has limited solubility in water. It is primarily used as a solvent in laboratories and in the production of various chemicals, including refrigerants and pharmaceuticals. Chloroform is also known for its historical use as an anesthetic, although this practice has largely been discontinued due to safety concerns. Exposure to chloroform can pose health risks, including potential liver and kidney damage, and it is classified as a possible human carcinogen. Proper handling and storage are essential to minimize risks, and it should be used in well-ventilated areas with appropriate personal protective equipment.
