m-dPEG®₃₆-Azide (Azido-m-dPEG®₃₆) (QBD-10531)



m-dPEG®36-azide, product number QBD-10531, also known as azido-m-dPEG®36, is a monodispersed PEG product used in click chemistry applications. A non-reactive, charge-neutral methyl group and an alkyne-reactive azido group, respectively, terminate the two ends of the long (110 atoms), single molecular weight, discrete PEG (dPEG®) spacer. Both metal-catalyzed (Cu(I), Ru) azide-alkyne cycloaddition (CuAAC, RuAAC) and strain-promoted azide-alkyne cycloaddition (SPAAC) work with this product. Possible click chemistry-based applications for this product include the construction of dendrimers and hydrogels and the modification of alkyne-functionalized surfaces or biomolecules containing alkyne groups.


Unit Size100 mg, 1000 mg
Molecular Weight1642.95; single compound
Chemical formulaC₇₃H₁₄₇N₃O₃₆
Purity> 95%
SpacersdPEG® Spacer is 110 atoms and 131.2 Å
Typical solubility properties (for additional information contact Customer Support)Methylene chloride, Acetonitrile, DMAC, DMSO or water.
Storage and handling-20°C; Always let come to room temperature before opening; be careful to limit exposure to moisture and restore under an inert atmosphere; stock solutions can be prepared with dry solvent and kept for several days (freeze when not in use). dPEG® pegylation compounds are generally hygroscopic and should be treated as such. This will be less noticeable with liquids, but the solids will become tacky and difficult to manipulate, if care is not taken to minimize air exposure.
