3,4-Dinitrobenzoic Acid, is used for the synthesis of more complex compounds such as metabolites of Brimonidine. It is also a specific substrate of glutathione S-transferase (GST), that can be used for the enzyme imaging and studies. It is an important corrosion inhibitor and is also used in photography.

生产方法
由4-氨基-3-硝基甲苯在硫酸存在下与过硫酸钾反应生成3-硝基-4-亚硝基甲苯。再用重铬酸钾氧化得到3,4-二硝基苯甲酸。用此法制备该品的过程与2,5-二硝基苯甲酸完全相同,可参见该条目。 用作糖的定量分析试剂,也用于有机合成。
用途
