71612-25-4 7H-Furo(3,2-g)(1)benzopyran-7-one, 9-((3,7-dimethyl-2,6-octadienyl)oxy)- (CAS 71612-25-4), molecular formula C21H22O4 and molecular weight 338.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 71612-25-4 7H-Furo(3,2-g)(1)benzopyran-7-one, 9-((3,7-dimethyl-2,6-octadienyl)oxy)- (C21H22O4) is characterized by a flavonoid 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 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.
