The molecular framework of 1-(5-BROMO-2-HYDROXY-3-NITROPHENYL)ETHANONE 3'-BROMO-6'-HYDROXY-5'-NITROACETOPHENONE 3-BROMO-6-HYDROXY-5-NITROACETOPHENONE 5'-BROMO-2'-HYDROXY-3'-NITROACETOPHENONE 5'-BROMO-3'-NITRO-2'-HYDROXYACETOPHENONE 70978-54-0 BC003709 (C8H12BrNO4) is characterized by an amide group, a carboxylic acid 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).
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.
