Thiol PEG amine hydrochloride, Mp 5000

Thiol-PEG-Amine Hydrochloride is a bifunctional polyethylene glycol (PEG) derivative with a thiol (-SH) group for stable conjugation to metal surfaces and thiol-reactive compounds, and a primary amine (-NH₂) for coupling to carboxyl or aldehyde-functionalized molecules. The hydrochloride salt enhances solubility and stability. Its hydrophilic PEG backbone improves biocompatibility, reduces nonspecific interactions, and enhances solubility in aqueous systems, making it ideal for surface functionalization, bioconjugation, and nanomaterial stabilization.

Applications:
Bioconjugation & Drug Delivery: Functionalizes biomolecules and nanoparticles for targeted drug delivery and prolonged circulation.
Surface Functionalization: Modifies gold, glass, and silicon surfaces for biosensors and diagnostic applications.
Hydrogel & Polymer Chemistry: Enhances hydrophilicity and bioactivity in polymer networks for biomedical applications.
Nanoparticle Stabilization: Prevents aggregation and improves biocompatibility of gold, silver, and quantum dot nanoparticles.
