Estrone cyanate

Estrone cyanate, or estrone 3-O-cyanate, also known as estrocyanate, is an estrogen and an estrogen ester – specifically, the 3-O-cyanate ester of estrone – which was investigated for potential use in birth control pills but was found to be of relatively low potency and ultimately was never marketed.[1][2][3][4]
