Chemical Structure

(9Z,12Z,15Z,18Z,21Z)-tetracosa-9,12,15,18,21-pentaenoic acid CAS 68378-48-3 chemical structure

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, (9Z,12Z,15Z,18Z,21Z)-tetracosa-9,12,15,18,21-pentaenoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies (9Z,12Z,15Z,18Z,21Z)-tetracosa-9,12,15,18,21-pentaenoic acid (CAS 68378-48-3), a certified reference material (molecular formula C24H38O2, MW 358.56 g/mol) for analytical method development and quality control.

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), (9Z,12Z,15Z,18Z,21Z)-tetracosa-9,12,15,18,21-pentaenoic 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.
