General description

4-Aminobenzoic acid, also known as para-aminobenzoic acid (PABA), is utilized as a precursor in the synthesis of aromatic amines and azo dyes.[1][2]

Application

4-Aminobenzoic acid is used:
  • As a building block in the synthesis of Polyamides[3]
  • As a substrate in folic acid production[4]
  • In the synthesis of Schiff base[5]
  • As an organic ligand in metal-organic framework (MOFs) synthesis[6]
