Tos-PEG5-Boc is a PEG-based PROTAC linker designed for the synthesis of PROTACs. These molecules exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins by connecting a ligand for an E3 ubiquitin ligase and a ligand for the target protein. It has a molecular weight of 476.58 and a chemical formula of C22H36O9S. Its appearance is a viscous liquid, colorless to light yellow.

Azido-PEG5-alcohol is a polyethylene glycol (PEG) linker with a terminal azide and a terminal alcohol, used for bioconjugation and linker installation. The azide group enables copper-catalyzed and strain-promoted azide-alkyne cycloaddition reactions, while the PEG5 spacer improves solubility and flexibility for conjugation workflows.
- Terminal azide enables CuAAC and SPAAC click reactions.
- PEG5 spacer increases solubility and reduces steric hindrance.
- Suitable for use as a non-cleavable linker in conjugation chemistry.
- Colorless to light yellow liquid with high purity.
- Stable under recommended storage conditions for long-term use.
