CATO supplies (+/-)-13-Hydroxy-9Z,11E-octadecadienoic acid,cholesterylester (9Z,11E)-((3S,8S,9S,10R,13R,14S,17R)-10,13-dimethyl-17-((R)-6-methylheptan-2-yl)-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-3-yl) 13-hydroxyoctadeca-9,11-dienoate 167354-91-8 (CAS 167354-91-8), a certified reference material (molecular formula C45H76O3, MW 665.08 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (+/-)-13-Hydroxy-9Z,11E-octadecadienoic acid,cholesterylester (9Z,11E)-((3S,8S,9S,10R,13R,14S,17R)-10,13-dimethyl-17-((R)-6-methylheptan-2-yl)-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-3-yl) 13-hydroxyoctadeca-9,11-dienoate 167354-91-8 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 665.08 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
