Description

Azido-PEG5-acid features a terminal azide group and carboxylic acid functionality separated by a five-ethylene glycol spacer. This bifunctional architecture enables efficient copper-free click chemistry conjugations while maintaining aqueous solubility and stability under standard handling conditions.

Application

Azido-PEG5-acid serves as a versatile bifunctional linker for bioconjugation and polymer chemistry, combining the stability of a PEG5 spacer with orthogonal reactivity. The azide group enables efficient copper-catalyzed (CuAAC) or strain-promoted (SPAAC) cycloaddition, while the terminal carboxylic acid facilitates amide coupling or activation via standard reagents. Its well-defined structure ensures consistent conjugation yields, ease of purification, and compatibility with diverse biomolecules and solid-phase workflows.
