Avobenzone-¹³C,d₃ 

Avobenzone-¹³C,d₃ is the ¹³C- and deuterium labeled Avobenzone. Avobenzone, a dibenzoylmethane compound, is one of the most widely used filters in sunscreens for skin photoprotection in the UVA band. Avobenzone is an endocrine disruptor that directly binds to estrogen receptor β and acts as an estrogen agonist[1][2].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[40].
