Aminooxy-PEG3-N3 (Aminooxy-PEG3-azide) is a bifunctional crosslinker featuring an aminooxy group and an azide group. The azide group readily participates in Click Chemistry reactions with alkyne, BCN, or DBCO groups, forming stable triazole linkages. The aminooxy group is highly reactive in bioconjugation applications, enabling the functionalization of biomolecules.

This versatile linker is classified as a PEG-based ADC linker, specifically a three-unit PEG, and is commonly used in the synthesis of antibody-drug conjugates (ADCs) and other bioconjugate molecules. 

Biopharma PEG offers a wide range of PEG linkers on both lab and commercial scales. Email at sales@biochempeg.com and start using a superior product for your next product R&D project.
