Used in research to study inflammatory processes and lipid signaling pathways. Acts as a precursor in the biosynthesis of pro-inflammatory mediators like leukotrienes and lipoxins. Commonly employed in cell culture studies to investigate the role of eicosanoids in immune responses, asthma, and other inflammatory diseases. Also used as a reference standard in analytical methods such as HPLC and mass spectrometry for eicosanoid profiling in biological samples.
