3,5-Dinitrobenzoic acid Usage And Synthesis

Chemical Properties

white or off-white solid

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.

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.

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.]
