Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ethyl (4Z,7Z,10Z,13Z,16Z,19Z)-henicosa-4,7,10,13,16,19-hexaenoate.

ethyl (4Z,7Z,10Z,13Z,16Z,19Z)-henicosa-4,7,10,13,16,19-hexaenoate (CAS CATO-C4X-280645) is a high-purity analytical reference standard with the molecular formula C23H34O2 and a molecular weight of 342.51 g/mol.

ethyl (4Z,7Z,10Z,13Z,16Z,19Z)-henicosa-4,7,10,13,16,19-hexaenoate (C23H34O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), ethyl (4Z,7Z,10Z,13Z,16Z,19Z)-henicosa-4,7,10,13,16,19-hexaenoate 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.
