Description

Application

3,4-Diaminobenzoic acid can be used to prepare:

Schiff base derivatives by reacting with substituted aldehydes and their corresponding metal complexes.
Poly(2,5-benzimidazole) (ABPBI) polymer by reacting with methanesulfonic acid and P₂O₅.
Pt-based Schiff base complexes applicable in H₂O splitting reactions.

3,4-Diaminobenzoic acid undergoes cyclocondensations to form, for example, quinoxalines and benzimidazoles.
