Chloroform

CHCl3, historical anaesthetic and common solvent

Chloroform, or trichloromethane (often abbreviated as TCM), is an organochloride with the formula CHCl3 and a common solvent. It is a volatile, colorless, sweet-smelling, dense liquid produced on a large scale as a precursor to refrigerants and polytetrafluoroethylene (PTFE). Chloroform was once used as an inhalational anesthetic between the 19th century and the first half of the 20th century.
