4,4,5,5,5-Pentafluoro-1-pentanethiol

Product Overview

4,4,5,5,5-Pentafluoro-1-pentanethiol is a highly specialized fluorinated organic compound characterized by the presence of a terminal sulfhydryl group and a perfluorinated alkyl chain. This unique molecular architecture combines the nucleophilic reactivity of thiols with the metabolic stability and lipophilicity imparted by fluorine atoms. As a critical chemical building block, it serves an essential role in the multi-step synthesis of complex pharmaceutical agents. Our facility produces this intermediate under strict quality control standards to ensure consistency for downstream medicinal chemistry applications.

The introduction of fluorine into organic molecules is a cornerstone strategy in modern drug design, often enhancing binding affinity and biological half-life. This pentafluoro-substituted thiol provides chemists with a versatile handle for constructing sulfur-containing motifs within larger therapeutic scaffolds. It is particularly valued in the preparation of oncology-related pharmaceutical precursors, including pathways leading to agents like Fulvestrant. We supply this material to research institutions and pharmaceutical manufacturers globally.
