Properties of Chloroform (CHCl3)
Chloroform is a volatile organic compound with the chemical formula CHCl3. It is a colorless, heavy, sweet-smelling liquid that was historically used as an anesthetic in the 19th and early 20th centuries. However, due to its toxic and potentially harmful effects on the liver and nervous system, its use in medicine has been largely discontinued.
