5-Bromo-2,3-difluoro-1-nitrobenzene can be used as a synthesis precursor to prepare 4-(benzyloxy)-N'-(4-bromo-2-fluoro-6-nitrophenyl)benzhydrazide by reacting with 4-benzyloxybenzhydrazide in dry DMSO[1].

5-Bromo-2,3-difluoro-1-nitrobenzene can be prepared by the bromination of 2,3-difluoronitrobenzene with NBS in sulfuric acid with the addition of trifluoroacetic acid[1].
