Description

Compared with other compounds in its class, the molecular weight of 354.53 g/mol gives (3E,6E,9E,12E,15E,18E,21E)-tetracosa-3,6,9,12,15,18,21-heptaenoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3E,6E,9E,12E,15E,18E,21E)-tetracosa-3,6,9,12,15,18,21-heptaenoic acid (CAS CATO-C4X-289034), molecular formula C24H34O2 and molecular weight 354.53 g/mol, is a CATO reference standard with documented purity and traceability.

(3E,6E,9E,12E,15E,18E,21E)-tetracosa-3,6,9,12,15,18,21-heptaenoic acid (C24H34O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), (3E,6E,9E,12E,15E,18E,21E)-tetracosa-3,6,9,12,15,18,21-heptaenoic 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.
