OHPH, also known as<unk>  enanthate (OHPE), as well as 17α-hydroxyprogesterone<unk>  or 17α-hydroxypregn-4-ene-3,20-dione 17α-heptanoate, is a synthetic pregnane steroid and a derivative of progesterone and 17α-hydroxyprogesterone. It is a progestogen ester; specifically, it is the C17α<unk>  (enanthate) ester of 17α-hydroxyprogesterone. Analogues of OHPH include the more well-known medications<unk>  acetate and<unk>  caproate<unk>  hexanoate). The C3 benzilic acid hydrazone of OHPH,<unk>  benzilic acid hydrazone (OHPHBH), is known and has been studied in animals. In terms of chemical structure, OHPH is very similar to<unk>  caproate, differing from it only in having one additional carbon in its fatty acid ester chain.
