General description

2-Hydroxy-4-methoxybenzophenone (benzophenone-3) is commonly employed as a broad-band UV-filter in sunscreen cosmetic products. It protects skin from the deleterious effects of the sun. It is one of the sunscreen constituent and its trace determination in water samples by solid-phase microextraction (SPME) and gas chromatography with flame ionization and mass spectrometric detection has been reported.

Application

2-Hydroxy-4-methoxybenzophenone may be used in the following studies:
  • Synthesis of as poly[(2-hydroxy-4-methoxybenzophenone) propylene] (HMBP-PD), a polymeric ligand (resin) used for the synthesis of metal/ligand polychelates (metal-polymer complexes).
  • Analytical reagent for the gravimetric determination of Cu(II).
