In the title salt, C(5)H(6)BrN(2) (+)·C(7)H(6)NO(2) (-), the pyridine N atom of the 2-amino-5-bromo-pyridine mol-ecule is protonated. In the crystal, the protonated N atom and the 2-amino group are hydrogen-bonded to the carboxyl-ate O atoms via a pair of N-H⋯O

Model reducing-end oligosaccharides were successfully labeled by a brominated aromatic amine reagent, 2-amino-5-bromopyridine (ABP), through reductive amination. Using either a combination of liquid chromatography/electrospray ionization mass spectrometry (LC/ESI-MS) with in-source fragmentation or liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS), sequence
In the title adduct, C(5)H(5)BrN(2)·C(7)H(6)O(2), the carboxyl group of the benzoic acid mol-ecule is twisted away from the attached ring by 12.97 (11)°. The 2-amino-5-bromo-pyridine mol-ecules inter-act with the carboxylic group of neighbouring benzoic acid mol-ecules through N-H⋯O and O-H⋯N hydrogen
