What is Estradiol Valerate?
Estradiol Valerate is an estrogen ester derived from 17β-estradiol, employed in hormone replacement therapy, contraceptives, and menopausal treatment. It offers a prolonged release profile, facilitating less frequent dosing. The molecular weight is 308.4 g/mol, with typical purity standards exceeding 98%. Its synthesis involves esterification of estradiol with valeric acid, necessitating high-quality intermediates and stringent process controls.
