Hazard Information | Back Directory | [Chemical Properties]
white or off-white solid | [Uses]
3,5-Dinitrobenzoic acid, is used as a reagent used in the derivatization of resins and the determination of ampicillin. | [Uses]
3,5-nitrobenzoic acid is an important intermediate for organic synthesis, in the pharmaceutical industry for the synthesis sulfachrysoidine and for the detection of ampicillin. | [Application]
3,5-Dinitrobenzoic Acid is used in fluorometric analysis of creatinine (which is a determinant of kidney function). Also used as a reagent in the synthesis of several organic compounds including that of rhodanine derivatives that act as aldose reductase inhibitors. | [Definition]
ChEBI: A member of the class of benzoic acids that is benzoic acid in which the hydrogens at positions 3 and 5 are replaced by nitro groups. | [Preparation]
3,5-Dinitrobenzoic acid is synthesized by nitration of benzoic acid. Sulfuric acid was added to the dry reaction pot, and benzoic acid was added under stirring. Heat to 60°C, add fuming nitric acid dropwise, and complete the dropwise addition below 85°C. React at 80-85°C for 1 h, 100°C for 0.5-1h, and then heat up to 135°C for 2h. Leave overnight. The reaction solution was put into ice water to separate out crystals, filtered, washed with water and then washed with 50% ethanol to obtain 3,5-dinitrobenzoic acid. Yield 70%. | [General Description]
3,5-Dinitrobenzoic acid forms an adduct with 3,5-dimethylpyridine and the crystal structure of adduct has been studied at room temperature and 80K for both undeuterated and deuterated compounds. It forms 1:1 cocrystal with analgesic drug, ethenzamide and exists in two polymorphic forms. | [Purification Methods]
Crystallise the acid from distilled H2O or 50% EtOH (4mL/g). Dry it in a vacuum desiccator or at 70o over BaO under a vacuum for 6hours. [Beilstein 9 II 279, 9 III 1779, 9 IV 1242.] |
