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.

The Fourier Transform Raman and Fourier Transform infrared spectra of 3,4-diaminobenzoic acid (3,4-DABA) were recorded in the solid phase. Geometry optimizations were done without any constraint and harmonic-vibrational wave numbers and several thermodynamic parameters were calculated for the minimum energy

Preformed (99m)Tc chelates with an activated ester function are useful for the gentle labeling of proteins (precomplexation route). In this context, new heterobifunctional ligands derived from 2,3,5,6-tetrafluorophenyl (TFP) 3,4-diamino-benzoates (OC1, OC3, OC4) were synthesized. Their corresponding (99m)Tc-complexation and protein-conjugation characteristics
