(S,R,S)-AHPC-PEG4-NH2 is a von Hippel-Lindau (VHL) E3 ligase ligand-linker conjugate that couples an (S,R,S)-AHPC VHL ligand to a four-unit polyethylene glycol (PEG4) linker terminated in a primary amine. It is supplied as a white to off-white solid and is intended for use as a building block in PROTAC synthesis to enable conjugation of target-binding warheads.
- Provides a VHL-binding ligand with a PEG4 spacer and terminal primary amine for conjugation.
- High purity by LCMS (≈99.5%) suitable for research applications.
- Soluble in DMSO at high concentration (≈170 mg/mL); ultrasonic assistance may be required.
- Molecular weight approximately 663.83 g/mol and formulated as a solid for easy handling.
- Stable when stored as a powder at -20°C (long term) or 4°C (short term); store solutions at -80°C for extended stability.
