Chloroform
Chloroform has several laboratory uses, primarily as a solvent. Some common applications include:
- Extraction: Chloroform is often used to extract compounds from mixtures due to its ability to dissolve a wide range of organic substances.
- Purification: It’s used in purification processes, such as recrystallization, where impurities can be removed by dissolving the desired compound in chloroform and then allowing it to crystallize out.
- Analytical Chemistry: Chloroform can be used as a solvent in various analytical techniques, including chromatography and spectroscopy.
- Reaction Medium: It serves as a reaction medium for certain chemical reactions, particularly those involving organic compounds.
- Preservation: In some cases, chloroform is used to preserve biological samples for analysis, although this use is less common now due to its toxicity and potential health risks.
