2,4-Dinitrobenzoic acid was used in the spectrophotometric determination of diazepam in pure samples and in its pharmaceutical preparations. It was employed as chromophore probe for analysis of perfluorinated carboxylic acids in water by capillary zone electrophoresis. It can be used to produce 2,4-dinitro-benzoyl chloride.
