Azido-PEG5-acid is an azide-terminated five-unit polyethylene glycol (PEG5) acid linker used for bioconjugation and linker synthesis. It functions as a click-chemistry reagent capable of undergoing azide-alkyne cycloaddition reactions and is commonly used in PROTAC and antibody-drug conjugate assembly.
- Azide functional group enables copper-catalyzed and strain-promoted click reactions.
- Five-unit PEG spacer provides solubility and flexibility for conjugation.
- High purity supports synthetic and bioconjugation applications.
- Available in multiple pack sizes for scalable workflows.
- Stable under recommended storage conditions to preserve reactivity.

m-PEG3-succinimidyl carbonate is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
