Azido-PEG4-alcohol (N3-PEG4-OH), is a click chemistry reagent consisting of an azide and a terminal hydroxyl group. The terminal azide reacts with alkyne, BCN, DBCO via click chemistry, such as copper(I)-catalyzed, ruthenium-catalyzed, and strain-promoted azide-alkyl cyclization reactions (CuAAC, RuAAC, and SPAAC, respectively). Without modification, the alcohol group increases the water solubility and the hydrodynamic volume of the molecules and surfaces to which it is conjugated. Modification of the alcohol with reactive groups (e.g., chloride, tosylate,, or mesylate) allows Azido-PEG4-alcohol to function as a crosslinker by subsequent chemical manipulation.

Biopharma PEG offers a wide range of PEG products (e.g. Azido-PEG4-alcohol) for click chemistry reactions including CuAAC, RuAAC, and SPAAC reactions. We are able to provide click chemistry reagents from lab to commercial scale in both non-GMP and GMP grades.
