(2E,4E,6E,8E,10E,12E)-docosa-2,4,6,8,10,12-hexaenoic acid CAS 25167-62-8

Description

The occurrence of (2E,4E,6E,8E,10E,12E)-docosa-2,4,6,8,10,12-hexaenoic acid is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2E,4E,6E,8E,10E,12E)-docosa-2,4,6,8,10,12-hexaenoic acid (CAS 25167-62-8) is a high-purity analytical reference standard with the molecular formula C22H32O2 and a molecular weight of 328.49 g/mol.

The molecular framework of (2E,4E,6E,8E,10E,12E)-docosa-2,4,6,8,10,12-hexaenoic acid (C22H32O2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), (2E,4E,6E,8E,10E,12E)-docosa-2,4,6,8,10,12-hexaenoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
