Nonadecanoic Acid methyl ester

Nonadecanoic Acid methyl ester (CAS No.: 1731-94-8) is a long-chain fatty acid methyl ester widely used as a reference compound in lipidomics and analytical biochemistry, particularly as an internal standard for the quantitative determination of fatty acid methyl esters in complex biological and industrial samples. Derived from nonadecanoic acid, a naturally occurring saturated fatty acid found in plant oils and animal fats, this esterified form exhibits reduced water solubility and improved compatibility with chromatographic systems, enabling stable and reproducible signal generation during gas and liquid chromatography-based analyses. Its primary function in research is to normalize variations arising from sample preparation, extraction efficiency, and instrument response, thereby enhancing the accuracy and reliability of lipid profiling studies, including investigations of metabolic disorders and lipid-associated diseases. While not a direct pharmacological agent, its parent fatty acid has been reported to inhibit proliferation of certain leukemia cell lines at low micromolar concentrations, suggesting potential relevance in studies of lipid-mediated cellular regulation, although specific molecular targets and signaling pathways remain insufficiently characterized. In experimental settings, this compound is commonly applied in analytical workflows, biodiesel composition analysis, and lipid metabolism research, with concentrations tailored to assay requirements and instrument sensitivity, supporting its role as a critical tool in both biomedical research and applied chemical analysis.
