Aminooxy-PEG2-azide(CAT: I014048) is a versatile heterobifunctional linker featuring an aminooxy group and an azide moiety connected by a short PEG2 spacer. The aminooxy group reacts efficiently with aldehydes and ketones to form stable oxime linkages, while the azide enables click chemistry reactions, such as CuAAC or SPAAC, for rapid and selective bioconjugation. The PEG2 spacer enhances aqueous solubility and reduces steric hindrance, making this reagent suitable for labeling, crosslinking, and drug delivery applications. Aminooxy-PEG2-azide is widely used in chemical biology, glycobiology, and materials science for constructing multifunctional biomolecules and site-specific conjugates with high stability and efficiency.
