Eicosapentaenoic acid (EPA) is an ω-3 fatty acid which can have beneficial effects on vascular and immune physiology. Also, EPA serves as a precursor for resolvins, mediators that help resolve inflammatory processes. EPA methyl ester is a more lipid-soluble form of EPA. This compound may be more desirable than the free acid in certain formulations. In addition, the methyl ester form of EPA may serve as a prodrug, since it should facilitate uptake of EPA and then be hydrolyzed by esterases to generate the free acid after uptake into cells.

Development of certified reference materials for four polyunsaturated fatty acid esters
Food Chem 2022 Sep 30;389:133006.PMID:35561511DOI:10.1016/j.foodchem.2022.133006.
Certified reference materials (CRMs) with high accuracy and traceability are essential tools for the validation of analytical methods and calibration of equipment. In this study, purity CRMs for four polyunsaturated fatty acids (PUFAs) esters, namely, cis-(4,7,10,13,16,19)- Docosahexaenoic acid methyl ester (DHA-ME), cis-4,7,10,13,16,19- Docosahexaenoic acid ethyl ester (DHA-EE), cis-(5,8,11,14,17)- Eicosapentaenoic Acid methyl ester (EPA-ME) and cis-(5,8,11,14,17)- Eicosapentaenoic acid ethyl ester (EPA-EE), were first developed according to the ISO Guide. The CRMs' purity values were assigned based on the average of quantitative nuclear magnetic resonance and mass balance approaches. The certified value with expanded uncertainties (k = 2, 95% confidence interval) were determined to be (98.8 ± 0.4) %, (99.0 ± 0.3) %, (98.9 ± 0.4) % and (98.9 ± 0.4) % for DHA-ME, DHA-EE, EPA-ME and EPA-EE, respectively. The four PUFAs esters were homogeneous and stable for 12 months at -4 °C and 7 days at 50 °C.
