Compared with other compounds in its class, the molecular weight of 334.54 g/mol gives cis-8,11,14-Eicosatrienoic Acid Ethyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
cis-8,11,14-Eicosatrienoic Acid Ethyl Ester (CAS 55968-21-3), molecular formula C22H38O2 and molecular weight 334.54 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of cis-8,11,14-Eicosatrienoic Acid Ethyl Ester (C22H38O2) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
