General description

Chloroform is a volatile chlorinated organic solvent whose vapors have a narcotic effect. Due to its light sensitivity, it may undergo degradation with time. This can be suppressed by adding ethanol as a stabilizer. The addition will increase the polarity of the solvent and potentially impact certain applications.

Application

Chloroform has been used as a solvent for dissolving lipids and also as a cleansing agent. It may also be used in solvent extraction process and also for recrystallization.
