Chemical Structure
Description
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 supplies cis-4,7,10,13,16,19-Docosahexaenoic Acid Methyl Ester (CAS 2566-90-7), a certified reference material (molecular formula C23H34O2, MW 342.51 g/mol) for analytical method development and quality control.
The molecular framework of cis-4,7,10,13,16,19-Docosahexaenoic Acid Methyl Ester (C23H34O2) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), cis-4,7,10,13,16,19-Docosahexaenoic Acid Methyl Ester 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.
