Hydroxyl PEG tritylthiol, Mp 10000

Hydroxyl PEG Tritylthiol is a bifunctional polyethylene glycol (PEG) derivative featuring a hydroxyl (-OH) group and a trityl-protected thiol (-SH). The trityl group serves as a protective moiety, allowing selective deprotection for controlled thiol reactivity. This PEG derivative is highly soluble in aqueous and organic solvents and is useful in applications requiring site-specific conjugation.

Applications:
Hydrogel Crosslinking: Acts as a thiol-functionalized macromer for thiol-ene or disulfide crosslinked hydrogels.
Nanoparticle Functionalization: Provides a stable linker for gold, silver, and quantum dot surface modifications.
Bioconjugation & Drug Delivery: Enables thiol-based conjugation strategies for targeted therapeutics.
Surface Modification: Used in antifouling coatings and bio-interface engineering.
