(4E,8E,12E,16E)-4,8,13,17,21-Pentamethyldocosa-4,8,12,16,20-pentaenoic acid CAS 56882-00-9 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 (4E,8E,12E,16E)-4,8,13,17,21-Pentamethyldocosa-4,8,12,16,20-pentaenoic acid.

CATO supplies (4E,8E,12E,16E)-4,8,13,17,21-Pentamethyldocosa-4,8,12,16,20-pentaenoic acid (CAS 56882-00-9), a certified reference material (molecular formula C27H44O2, MW 400.64 g/mol) for analytical method development and quality control.

(4E,8E,12E,16E)-4,8,13,17,21-Pentamethyldocosa-4,8,12,16,20-pentaenoic acid (C27H44O2) 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.

As a certified reference material (CRM), (4E,8E,12E,16E)-4,8,13,17,21-Pentamethyldocosa-4,8,12,16,20-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.
