Estriol dihexanoate, or estriol 3,17β-dihexanoate, is a synthetic estrogen and estrogen ester – specifically, the C3 and C17β dihexanoate ester of estriol – which was first described in 1963 and was never marketed. Following a single intramuscular injection of 8.90 mg estriol dihexanoate (equivalent to 5.0 mg estriol) in an oil solution, peak levels of estriol occurred after 2.1–3.4 days, a terminal half-life of 187–221 hours was observed, and estriol levels remained elevated for up to 20–50 days. For comparison, the durations of estriol and estriol dipropionate were far shorter.
