Application

Chloroform (spectrophotometric grade) was used in the following processes:Synthesis of colloidal hydrophobic CdSe core nanocrystals (quantum dots).Preparing phospholipid solutions.As a solvent in the photolysis reaction of ruthenium complexes.It may be used as:Solvent for recrystallization.Reference compound to detect the presence of chloroform in Tobacco smokes.Extractant in solvent extraction process.

General description

Chloroform is a is a colorless, volatile chlorinated organic solvent whose vapors have narcotic effect. It is susceptible to degradation with time which can be suppressed by adding ethanol as a stabilizer. Since ethanol is added in higher concentration it leads to increase in polarity which may have a potential influence on some of the applications. Spectrophotometric grade chloroform shows low UV absorption which makes it an ideal solvent for spectrophotometry.
