Estradiol valerate is a synthetic estrane steroid and the C17β valerate (pentanoate) fatty acid ester of estradiol.
It is also known as estradiol 17β-valerate or as estra-1,3,5(10)-triene-3,17β-diol 17β-pentanoate.
Other common esters of estradiol in use include estradiol cypionate, estradiol enantate, and estradiol acetate, the former two of which are C17β esters of estradiol similarly to estradiol valerate and the latter of which is the C3 acetate ester of estradiol.

The experimental octanol/water partition coefficient (logP) of estradiol valerate is 5.6 to 6.3.
