| 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. |
