Estradiol furoate

Estradiol furoate (EF), or estradiol 17β-furoate, sold under the brand name Di-Folliculine, is an estrogen medication and estrogen ester which is no longer marketed.[1] It is the C17β furoate ester of estradiol.[1] Estradiol benzoate has also been marketed under the brand name Di-Folliculine, and should not be confused with estradiol furoate.[2]

Not to be confused with Estradiol benzoate or Estrofurate.

The duration of action of the related estradiol ester estradiol 3-furoate by intramuscular injection was studied in women in 1952.[3] Its duration in oil solution was found to be similar to that of estradiol benzoate in oil solution and shorter than that of estradiol dipropionate in oil solution.[3]
