| Hazard Information | Back Directory | [Chemical Properties]
yellowish crystals or crystalline powder | [Uses]
3,4-Dinitrobenzoic Acid, is used for the synthesis of more complex compounds such as metabolites of Brimonidine (B677520). 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. | [Purification Methods]
Crystallise the acid from EtOH by addition of water. [Beilstein 9 III 1778, 9 IV 1242.] |
