Chemical Structure

2-NITRO-5-BROMOBENZOIC ACID 5-BROMO-2-NITRO-BENZOIC ACID 6950-43-2 BC004551 BENZOIC ACID, 5-BROMO-2-NITRO- CAS 6950-43-2 chemical structure

Description

The molecular framework of 2-NITRO-5-BROMOBENZOIC ACID 5-BROMO-2-NITRO-BENZOIC ACID 6950-43-2 BC004551 BENZOIC ACID, 5-BROMO-2-NITRO- (C7H4BrNO4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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).
