Chemical Structure
Description
The molecular framework of 3-Amino-2-bromo-4H-chromen-4-one (C9H6BrNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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-Amino-2-bromo-4H-chromen-4-one (CAS 61423-68-5) is a high-purity analytical reference standard with the molecular formula C9H6BrNO2 and a molecular weight of 240.05 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
