Estradiol valerate (EV, E2V) (INN, USAN, JAN) (brand names Altadiol, Deladiol, Delestrogen, Estraval, Lastrogen, Progynova, Valergen, many others), or oestradiol valerate (BAN), is a synthetic ester, specifically the 17-pentanoyl ester, of the natural estrogen, 17β-estradiol. It was first introduced, as Delestrogen by Squibb in the United States, in 1954, and along with estradiol benzoate (1936) and estradiol cypionate (1952), has since become one of the most widely used esters of estradiol.
