Application:

Avobenzone may be used as an analytical reference standard for the quantification of the analyte in the following:

    • Sunscreen formulations using reversed-phase high-performance liquid chromatography with diode array detection (RP-HPLC-DAD).

   • Freshwater, saline water samples,[3] rat plasma and skin layers[4] using liquid chromatography-positive electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) in multiple reaction monitoring mode (MRM).

Avobenzone may be used to study the photophysical characteristics, photosensitizing activity of a blocked diketo form derived from 4-tert-butyl-4′-methoxydibenzoylmethane (BM-DBM).
