Chloroform is a volatile chlorinated organic solvent whose vapors have a narcotic effect. [ 1] 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. fern care home
