3,4-Diaminobenzoic acid Usage And Synthesis

Chemical Properties

brown powder

Uses

3,4-Diaminobenzoic acid undergoes cyclocondensations to form, for example, quinoxalines1 and benzimidazoles. It acts as a redox label for electrochemical detection of single base mismatches.

Purification Methods

Crystallise it from H2O or toluene. [Beilstein 15 IV 1503.]
