PEG methyl ether thiol, Mp 20000

PEG Methyl Ether Thiol (mPEG-SH) is a thiol (-SH) functionalized polyethylene glycol, commonly used for surface modification, thiol-ene click reactions, and redox-sensitive polymer applications. The PEG backbone enhances solubility and steric stability, while the thiol group enables strong covalent bonding to metallic surfaces, proteins, and polymers.

Applications:
Surface Modification: Forms self-assembled monolayers (SAMs) on gold, silver, and other metal surfaces, improving biointerface properties.
Bioconjugation & Drug Delivery: Reacts with maleimide-functionalized molecules for targeted nanoparticle and drug carrier functionalization.
Hydrogel Crosslinking: Enables thiol-based crosslinking in biodegradable hydrogel networks for controlled drug release and tissue scaffolds.
Electrochemical Sensors: Enhances stability and antifouling properties in biosensors and medical diagnostic platforms.
