Isopelargonic acid is a monocarboxylic acid with versatile applications in the identification and characterization of polycarboxylic acids. This compound enables the analysis of various carboxylic acids and fatty acid esters, including isovaleric acid and its esters. Furthermore, isopelargonic acid is utilized as an organic solvent for the extraction of fatty alcohols from plants. Its functionality extends to the production of fatty acids, as it facilitates the introduction of hydroxyl groups into the molecular structure.
