Description and Uses

4,4,5,5,5-Pentafluoro-1-pentanol (PFP; Pentafluoropentanol) is an essential building block primarily used in the commercial manufacture of the API. It is typically activated with a sulfonate leaving group and displaced selectively by the sulfur atom in 9-mercapto-1-nonanol to make 9-[(4,4,5,5,5-pentafluoropentyl)-thio]-1-nonanol (FVS). FVS is subsequently converted into a bromide and coupled with the steroid portion to make fulvestrant. First approved by the FDA in 2002, fulvestrant is a medication used to treat hormone receptor (HR)-positive metastatic breast cancer in postmenopausal women with disease progression.

4,4,5,5,5-Pentafluoro-1-pentanol may be used in the preparation of chlorine-capped telechelic poly(methyl methacrylate)s.
