Chemical Structure

3-(4-hydroxyphenyl)-4-oxo-4H-chromen-7-yl dihydrogen phosphate CAS 386285-65-0 chemical structure

Description

The molecular framework of 3-(4-hydroxyphenyl)-4-oxo-4H-chromen-7-yl dihydrogen phosphate (C15H11O7P) is characterized by a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).

3-(4-hydroxyphenyl)-4-oxo-4H-chromen-7-yl dihydrogen phosphate (CAS 386285-65-0), molecular formula C15H11O7P and molecular weight 334.22 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.
