Application

p-Phenylenediamine (1,4-Phenylenediamine or PPDA) can be used as a precursor for the synthesis of asymmetric bis-schiff bases , angular diazatricycles , poly (p-phenylenediamine) and aromatic polyamides.
It can also be used as a reactant in the synthesis of azo-schiff-base complexes of various metals.
