E3 ligase Ligand-Linker Conjugate 32 is a conjugate of E3 ligase ligand and linker , consisting of (S,R,S)-AHPC and the corresponding Linker. (S,R,S)-AHPC is a VH032-based von Hippel-Lindau (VHL) ligand that recruits VHL proteins. E3 ligase Ligand-Linker Conjugate 32 can be used as a key intermediate for the synthesis of complete PROTAC molecules.
