Application
o-Phenylenediamine can be used in the synthesis of:
- Various benzimidazole derivatives that are structural units of several bioactive drug substances and pigments.
- N-doped colloidal graphene quantum dots (QDs), which can electrochemically catalyze the oxygen reduction reactions.
- N-doped graphene nanoplatelets from simple solution edge-functionalization for n-type field-effect transistors.
- N-heteroacenes (azaacenes) that are good candidates as active materials for organic thin film transistors.

Present study is designed for the synthesis, characterization and corrosion inhibition behavior of two diamine aromatic epoxy pre-polymers (DAEPs) namely, N1,N1,N2,N2-tetrakis (oxiran-2-ylmethyl) benzene-1,2-diamine (DAEP1) and 4-methyl-N1,N1,N2,N2-tetrakis (oxiran-2-ylmethyl) benzene-1,2-diamine (DAEP2) for carbon steel corrosion in acidic medium. Synthesized DAEPs were characterized
