Chemical Structure

(5Z,8E,11E,14Z,17Z)-5,8,11,14,17-Ethyl Eicosapentaenoate CAS CATO-C4X-289012 chemical structure

Description

Structurally, (5Z,8E,11E,14Z,17Z)-5,8,11,14,17-Ethyl Eicosapentaenoate (C22H34O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 330.50 g/mol, it falls into the moderately-high-molecular-weight range. 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).

(5Z,8E,11E,14Z,17Z)-5,8,11,14,17-Ethyl Eicosapentaenoate (CAS CATO-C4X-289012), molecular formula C22H34O2 and molecular weight 330.50 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
