N-(Azido-PEG2)-N-Boc-PEG4-Boc
blur_circular Chemical Specifications
description Product Description
This chemical is widely used in bioconjugation and click chemistry applications due to its dual functional groups. The azide group enables efficient and selective reactions with alkynes via copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable for labeling biomolecules such as proteins, peptides, and nucleic acids. The Boc-protected amine group provides a convenient handle for further modifications after deprotection, allowing for the introduction of additional functional groups or linkers. Its PEG (polyethylene glycol) spacers enhance solubility and reduce steric hindrance, making it particularly useful in drug delivery systems, surface functionalization, and the development of biomaterials. Additionally, it is employed in the synthesis of targeted therapeutics, diagnostics, and imaging agents, where precise control over molecular interactions is critical.
