N-(4-Bromophenyl)-4-hydroxy-2-oxo-1-pentyl-1,2-dihydroquinoline-3-carboxamide (CAS 300716-31-8) is a high-purity analytical reference standard with the molecular formula C21H21BrN2O3 and a molecular weight of 429.31 g/mol.
The molecular framework of N-(4-Bromophenyl)-4-hydroxy-2-oxo-1-pentyl-1,2-dihydroquinoline-3-carboxamide (C21H21BrN2O3) is characterized by a steroid core, 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. 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.
