Chloroform

CHCl3, historical anaesthetic and common solvent

Chloroform, or trichloromethane, is an organochloride with the formula CHCl3 and a common solvent. It is a very volatile, colorless, strong-smelling, dense liquid produced on a large scale as a precursor to refrigerants and PTFE. Chloroform is a trihalomethane that serves as a powerful general anesthetic, euphoriant, anxiolytic, and sedative when inhaled or ingested; for this reason, Chloroform was used as an inhalational anesthetic between the 19th century and the first half of the 20th century. It is miscible with many solvents but it is only very slightly soluble in water.
