Hexacosanoic acid is classified under the very long chain fatty acids (VLCFAs) group of biologically important compounds.

• Identity confirmed by LC-MS method

Used as a reference standard for the determination of hexacosanoic acid in human serum and plasma samples for the screening of peroxisomal disorders by gas chromatography-mass spectrometry (GC-MS) operating under selected-ion monitoring (SIM) mode, in biological samples by GC-MS, in microalgal lipids by solid-phase extraction (SPE) followed by GC-MS analysis as a naphthoxyethyl derivative by high performance liquid chromatography (HPLC) coupled with fluorometric detection.
