Chemical Structure

Lipoxin A4 CAS 89663-86-5 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 Lipoxin A4 (CAS 89663-86-5), a certified reference material (molecular formula C20H32O5, MW 352.47 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, Lipoxin A4 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 352.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Lipoxin A4 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.
