Uses
Before the Montreal Protocol, chlorodifluoromethane (designated as R-22) was also a popular refrigerant.
Solvent Worldwide, chloroform is also used in pesticide formulations, as a solvent for fats, oils, rubber, alkaloids, waxes, gutta-percha, and resins, as a cleansing agent, grain fumigant, in fire extinguishers, and in the rubber industry. CDCl3 is a common solvent used in NMR spectroscopy.
Reagent Chloroform serves as a source of the dichlorocarbene CCl2 group. It reacts with aqueous sodium hydroxide usually in the presence of a phase transfer catalyst to produce dichlorocarbene, CCl2.
Anesthetic The use of chloroform during surgery
Criminal use
Chloroform has been reputed to be used by criminals to knock out, daze or even murder their victims.
