Application

(S,R,S)-AHPC (HCl salt) is a ligand used in the recruitment of the von Hippel-Lindau (VHL) protein for targeted protein degradation and PROTAC (proteolysis-targeting chimeras) technology. This (S,R,S) conformation is the active variant, and (S,S,S) is the inactive derivative (cat#901487) used as a negative control.
