Application

4-Hydroxybenzaldehyde can be used as a reactant to synthesize:
  •  4-Hydroxybenzaldehydesemicarbazone by a condensation reaction with semicarbazide.    
  • 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.
  • (−)-Centrolobine, a diarylheptanoid.

A series of novel 4-hydroxybenzaldehyde derivatives were synthesized and their inhibitory effects on the diphenolase activity of mushroom tyrosinase were investigated. Most of target compounds had more potent inhibitory activities than the parent compound 4-hydroxybenzaldehyde (IC(50)=1.22 mM). Interestingly, compound 3c
