Description
The occurrence of (+/-)-9-Hydroxy-10E,12Z-octadecadienoic acid,cholesterylester (10Z,12Z)-((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) 9-hydroxyoctadeca-10,12-dienoate 33783-76-5 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (+/-)-9-Hydroxy-10E,12Z-octadecadienoic acid,cholesterylester (10Z,12Z)-((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) 9-hydroxyoctadeca-10,12-dienoate 33783-76-5 (CAS 33783-76-5), a certified reference material (molecular formula C45H76O3, MW 665.08 g/mol) for analytical method development and quality control.
Structurally, (+/-)-9-Hydroxy-10E,12Z-octadecadienoic acid,cholesterylester (10Z,12Z)-((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) 9-hydroxyoctadeca-10,12-dienoate 33783-76-5 (C45H76O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 665.08 g/mol, it falls into the high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
