Haloprogesterone, also known as 6α-fluoro-17α-bromoprogesterone or as 6α-fluoro-17α-bromopregn-4-ene-3,20-dione, is a synthetic pregnane steroid and a halogenated derivative of progesterone. It is specifically a derivative of 17α-bromoprogesterone and is similar structurally to medrogestone (6-dehydro-6,17α-dimethylprogesterone), medroxyprogesterone acetate (6α-methyl-17α-acetoxyprogesterone), and various other progestins derived from progesterone.
Haloprogesterone was marketed under the brand name Prohalone.
