Chemical Structure
Description
3-Amino-5-bromo-3,4-dihydroquinolin-2(1H)-one hydrochloride (C9H9BrN2OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
3-Amino-5-bromo-3,4-dihydroquinolin-2(1H)-one hydrochloride (CAS 2766577-11-9) is a high-purity analytical reference standard with the molecular formula C9H9BrN2OHCl and a molecular weight of 277.55 g/mol.
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.
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.
