3-(5-Amino-2-bromo-4-fluorophenyl)-7-chloro-1-ethyl-1,6-naphthyridin-2(1H)-one CAS 1442470-52-1

Description

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.

3-(5-Amino-2-bromo-4-fluorophenyl)-7-chloro-1-ethyl-1,6-naphthyridin-2(1H)-one (CAS 1442470-52-1) is a high-purity analytical reference standard with the molecular formula C16H12BrClFN3O and a molecular weight of 396.64 g/mol.

Based on its molecular formula C16H12BrClFN3O, 3-(5-Amino-2-bromo-4-fluorophenyl)-7-chloro-1-ethyl-1,6-naphthyridin-2(1H)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 396.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
