The molecular framework of 4,9-Dimethoxy-6-methyl-8H-furo[2,3-g]chromen-8-one (C14H12O5) 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 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).
CATO supplies 4,9-Dimethoxy-6-methyl-8H-furo[2,3-g]chromen-8-one (CAS 114191-63-8), a certified reference material (molecular formula C14H12O5, MW 260.24 g/mol) for analytical method development and quality control.
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.
