Estradiol-¹³C₂  (Synonyms: β-Estradiol-¹³C₂; E2-¹³C₂; 17β-Estradiol-¹³C₂; 17β-Oestradiol-¹³C₂)

Estradiol-¹³C₂ is the ¹³C-labeled Estradiol. Estradiol is a steroid sex hormone vital to the maintenance of fertility and secondary sexual characteristics in females. Estradiol upregulates IL-6 expression through the estrogen receptor β (ERβ) pathway[1][2][3].

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^[1].
