CATO supplies 3-Bromo-4-hydroxy-2H-chromen-2-one, 97% (CAS 2650-14-8), a certified reference material (molecular formula C9H5BrO3, MW 241.04 g/mol) for analytical method development and quality control.
The molecular framework of 3-Bromo-4-hydroxy-2H-chromen-2-one, 97% (C9H5BrO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
