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.

Butylated hydroxytoluene (BHT) containing the stable isotope 13C was synthesized from 2-[13C]methylpropan-2-ol. A minor constituent of urine following ingestion of BHT-13C by a human volunteer was identified as 3,5-di-(1-[13C]methyl-1-methylethyl)-4-hydroxybenzoic acid, The major metabolite detected was 13C-labeled 5-carboxy-7-(1-carboxy-1-methylethyl)-3,3-dimethyl-2-hydroxy-2,3-dihydrobenzofuran.
