Product Overview

Chloroform 99.8% AR (CAS No. 67-66-3) is an analytical-reagent form of trichloromethane, a dense chlorinated solvent with strong affinity for many non-polar and moderately polar organic compounds. Its limited miscibility with water and efficient partitioning behaviour make it particularly relevant to extraction, sample cleanup and concentration procedures.

The AR grade is intended for precise analytical work of a general nature, including reagent preparation, solvent extraction and extraction–concentration analysis. Its analytical positioning supports controlled reagent cleanliness, making it a suitable choice for most routine and analytical laboratory analyses.

Typical Applications

• Liquid–liquid extraction of suitable organic analytes from aqueous samples.
• Extraction–concentration procedures followed by solvent removal or exchange.
• Preparation of analytical reagent and sample solutions.
• Solvent and procedural blanks in validated conventional analytical methods.
• Partition, recovery and sample-cleanup studies involving hydrophobic analytes.
• Laboratory quality-control procedures requiring analytical-reagent chloroform.

Common Synonyms

• Trichloromethane
• Methane Trichloride
• Methyl Trichloride
• Trichloroform
• Chloroform

Storage Conditions

Keep the container tightly closed and protect from direct light, excessive heat, prolonged air exposure, evaporation and analytical contamination. Use clean dispensing equipment and minimise repeated opening to preserve reagent composition and blank cleanliness.
