m-PEG3-aldehyde (stabilized with BHT) is a short, methoxy-capped polyethylene glycol (PEG) aldehyde reagent used as a linker in PROTAC development and conjugation chemistry. Provided stabilized with BHT to limit oxidation, it supplies a three-unit PEG spacer terminated with an aldehyde for chemoselective coupling reactions.

• Aldehyde-terminated PEG spacer for bioconjugation and PROTAC synthesis.
• Methoxy-capped terminus to prevent undesired side reactions.
• Short PEG3 length for controlled linker distance.
• Stabilized with BHT to reduce oxidative degradation during storage.
• High purity suitable for research applications (98.0%).
• Available in small research pack sizes, including 25 MG.
