General description

4-Hydroxybenzoic acid is an aromatic carboxylic acid commonly used as a building block in various organic reactions, such as in the synthesis of liquid crystals and parabens. It is also utilized in esterification reactions for synthesizing aromatic oligomers.

Application

4-Hydroxybenzoic acid can be used as a reactant to synthesize:
  • Monoesters via esterification with sucrose.
  • Thermotropic liquid crystalline polymers.
  • 4-Hydroxybenzaldoxime via one-pot chemoenzymatic method.
