Description

The molecular framework of 4418-73-9 PSZ3Q7662U Doradexanthin UNII-PSZ3Q7662U 3,3'-Dihydroxyechinenone 4-Keto-zeaxanthin All-trans-beta-doradexanthin beta-Doradexanthin beta,beta-Caroten-4-one, 3,3'-dihydroxy-, (3S,3'R)- Adonixanthin beta-Caroten-4-one, 3,3'-dihydroxy- (3S,3'R)-3,3'-Dihydroxy-beta,beta-caroten-4-one (3S,3'R)-4-Keto-zeaxanthin (3S,3'R)-Adonixanthin (C40H54O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

4418-73-9 PSZ3Q7662U Doradexanthin UNII-PSZ3Q7662U 3,3'-Dihydroxyechinenone 4-Keto-zeaxanthin All-trans-beta-doradexanthin beta-Doradexanthin beta,beta-Caroten-4-one, 3,3'-dihydroxy-, (3S,3'R)- Adonixanthin beta-Caroten-4-one, 3,3'-dihydroxy- (3S,3'R)-3,3'-Dihydroxy-beta,beta-caroten-4-one (3S,3'R)-4-Keto-zeaxanthin (3S,3'R)-Adonixanthin (CAS 4418-73-9), molecular formula C40H54O3 and molecular weight 582.85 g/mol, is a CATO reference standard with documented purity and traceability.

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), 4418-73-9 PSZ3Q7662U Doradexanthin UNII-PSZ3Q7662U 3,3'-Dihydroxyechinenone 4-Keto-zeaxanthin All-trans-beta-doradexanthin beta-Doradexanthin beta,beta-Caroten-4-one, 3,3'-dihydroxy-, (3S,3'R)- Adonixanthin beta-Caroten-4-one, 3,3'-dihydroxy- (3S,3'R)-3,3'-Dihydroxy-beta,beta-caroten-4-one (3S,3'R)-4-Keto-zeaxanthin (3S,3'R)-Adonixanthin 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.
