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.
