Collection: Esterification, Alkylation [GC Derivatization Reagents]

Esterification, Alkylation [GC Derivatization Reagents] — includes acid reagents in alcohol solvents, such as hydrogen chloride-methanol, boron trifluoride-methanol/isopropanol/butanol, and boron trichloride-methanol, which convert carboxylic acid groups into methyl or alkyl esters through acid catalysis.

These derivatization reagents are used by gas chromatography analysts to esterify fatty acids, organic acids, or polar metabolites into more volatile and stable methyl ester derivatives before analysis by GC or GC-MS. They are common in fatty acid profile analysis (FAME) in food, lipidomics, and environmental laboratories. The choice of alcohol type (methanol, butanol, isopropanol) is adjusted to the boiling point of the desired ester.
