Product number 10259, m-dPEG®7-Tosylate, is a short, methyl-terminated discrete PEG (dPEG®) product that can be used to modify surfaces, small molecules, and biomolecules. The single molecular weight PEG spacer contains a tosylate group at one end. The tosylate is an excellent leaving group in nucleophilic substitution reactions. Consequently, under appropriate reaction conditions, it reacts with amines, alcohols, thiols, and other similar reactive groups to form a stable bond. The short dPEG® spacer increases the hydrodynamic volume and water solubility of molecules to which it is conjugated. Also, coating surfaces and molecules with PEG reduces problematic hydrophobic and non-specific interactions.

Quanta BioDesign’s dPEG® products are used globally in clinical diagnostics and therapeutics. The single molecular weight character of our products gives them advantages over traditional polymer PEG products. If you want to learn more about our products, please visit the following pages.
