Application

4-Hydroxybenzaldehyde can be used as a reactant to synthesize:
  • Schiff Bases with optical properties through its reaction with anilines.
  • Vanillin via bromination followed by copper-catalyzed coupling reaction with sodium methoxide.
  • Oligo-4-hydroxybenzaldehyde by an oxidative polycondensation reaction with hydrogen peroxide (H2O2) in an alkaline medium.
