Estradiol plus the fatty acid valeric acid (valerate) equals estradiol valerate, a C17β ester of estradiol. [107] Estradiol valerate is a synthetic estrane steroid and the C17β valerate (pentanoate) fatty acid ester of estradiol. [23] [24] It is also known as estradiol 17β-valerate or as estra-1,3,5(10)-triene-3,17β-diol 17β-pentanoate.

The longer and hence more lipophilic the fatty acid ester, the slower the release from the depot, the lower the peak estradiol levels, and the longer the duration. [274] [10] [265] The duration of estradiol esters in oil solution by intramuscular injection is dose-dependent. [282]
Valeric acid or pentanoic acid is a straight-chain alkyl carboxylic acid with the chemical formula CH 3 (CH 2) 3 COOH. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor . It is found in the perennial flowering plant Valeriana officinalis , from which it gets its name.

Polyestradiol phosphate, a polymer of estradiol phosphate, the C17β phosphoric acid ester of estradiol. It has on average of 13 repeat units. Estradiol esters have an ester moiety, usually a straight-chain fatty acid (e.g., valeric acid) or an aromatic fatty acid (e.g., benzoic acid), attached at the C3 and/or C17β positions of the steroid ...
