Chemical Structure
Description
The molecular framework of 3-(4-Bromophenyl)-7-[(methylsulfonyl)oxy]-4-oxo-4H-chromene (C16H11BrO5S) is characterized by a flavonoid core, a sulfone group, 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).
CATO supplies 3-(4-Bromophenyl)-7-[(methylsulfonyl)oxy]-4-oxo-4H-chromene (CAS 610753-87-2), a certified reference material (molecular formula C16H11BrO5S, MW 395.22 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
