(5E,8E,11E,14E,17E)-icosa-5,8,11,14,17-pentaenoic acid CAS 1553-41-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5E,8E,11E,14E,17E)-icosa-5,8,11,14,17-pentaenoic acid.

(5E,8E,11E,14E,17E)-icosa-5,8,11,14,17-pentaenoic acid (CAS 1553-41-9), molecular formula C20H30O2 and molecular weight 302.45 g/mol, is a CATO reference standard with documented purity and traceability.

(5E,8E,11E,14E,17E)-icosa-5,8,11,14,17-pentaenoic acid (C20H30O2) 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).

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.

CATO manufactures (5E,8E,11E,14E,17E)-icosa-5,8,11,14,17-pentaenoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
