Chloroform Extra Pure is a high-purity, colorless, and volatile liquid commonly used in laboratory environments as a solvent, reagent, and extraction medium. Due to its excellent solvency for fats, alkaloids, and other organic compounds, it plays a key role in organic synthesis, chromatography, and sample preparation. In molecular biology, it is frequently used in nucleic acid extraction protocols. The extra pure grade ensures low levels of impurities, making it suitable for analytical and research applications that demand high accuracy. It must be handled with proper ventilation, protective equipment, and stored away from light and heat to prevent decomposition and formation of toxic by-products like phosgene.
Description
Chloroform Extra Pure
Primary Uses
- Organic Solvent for Extractions
- Widely used in liquid-liquid extraction, especially to isolate alkaloids, lipids, and other nonpolar compounds due to its high solubility for hydrophobic substances.
- DNA/RNA Extraction Reagent
- Essential in phenol-chloroform extraction protocols for separating nucleic acids from proteins in molecular biology labs.
- Reagent in Organic Synthesis
- Used in reactions involving halogenated intermediates, such as the Reimer–Tiemann reaction to form aromatic aldehydes from phenols.
- Sample Preparation for Spectroscopy
- Occasionally used to dissolve compounds before IR or NMR analysis when non-aqueous solvents are required.
Secondary Uses
- Cleaning Solvent in Analytical Labs
- Employed (with caution) for cleaning glassware or removing organic residues in delicate analytical setups.
- Solvent for Pesticide Residue Analysis
- Used in some GC-MS sample preps for dissolving or concentrating analytes from environmental or agricultural samples.
- Reference Material in Spectroscopy
- Chloroform-d (deuterated chloroform) is a standard solvent for ¹H and ¹³C NMR, but non-deuterated chloroform can also be used as a comparative solvent.
