Chemical Structure
Description
3-Amino-6-bromo-3,4-dihydroquinolin-2(1H)-one (CAS 127920-64-3) is a high-purity analytical reference standard with the molecular formula C9H9BrN2O and a molecular weight of 241.08 g/mol.
The molecular framework of 3-Amino-6-bromo-3,4-dihydroquinolin-2(1H)-one (C9H9BrN2O) 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 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.
As a certified reference material (CRM), 3-Amino-6-bromo-3,4-dihydroquinolin-2(1H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
