m-PEG3-aldehyde is a short polyethylene glycol (PEG)-based linker bearing a methoxy terminus and a reactive aldehyde group. It is supplied for research use and is used to introduce a flexible PEG3 spacer and an aldehyde functional handle in the synthesis of PROTACs, bioconjugates, and other medicinal chemistry applications. The compound is typically handled and stored under inert conditions and is soluble in DMSO.

  • Provides a PEG3 spacer for flexible linkage.
  • Contains a terminal aldehyde for chemoselective conjugation to hydrazide or aminooxy groups.
  • Suitable for PROTAC synthesis and bioconjugation workflows.
  • High reported purity for research applications.
  • Soluble in DMSO for preparation of stock solutions.

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.
