Chemical Properties White Crystalline Powder

Usage: Potent mammalian estrogenic hormone produced by the ovary.

Estradiol is the major estrogen secreted by the premenopausal ovary.

Biological Activity: Endogenous estrogen receptor (ER) agonist (K i values are 0.12 and 0.13 nM for ER α and ER β respectively). Also high affinity ligand at membrane estrogen GPR30 receptors.
