The molecular framework of 2-Bromo-1,3-bis(3,4-dimethoxyphenyl)propane-1,3-dione (C19H19BrO6) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. 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).
2-Bromo-1,3-bis(3,4-dimethoxyphenyl)propane-1,3-dione (CAS 832738-21-3), molecular formula C19H19BrO6 and molecular weight 423.25 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.
