General description

4-aminopyridine is a ligand and an ion channel modulator used as an acetylcholine release enhancing agent.

Application

4-Aminopyridine (4-AP) can be used as a:
  • Catalyst in the regioselective acylation of N-tosylhydrazide.
  • Starting material in the synthesis of 4-aminopyridine derivatives for neurological disorder studies.
  • Precursor for the synthesis of enantiomerically pure 4-(pyrrolidino)pyridine (PPY) derivatives by cyclocondensation reaction.
