Azido-PEG6-acid（Cat No.:I015986）is a polyethylene glycol linker composed of a six-unit PEG chain terminated with an azide group on one end and a carboxylic acid on the other. The PEG6 spacer enhances hydrophilicity, provides flexibility, and reduces steric hindrance, facilitating efficient conjugation. The azide functionality enables bioorthogonal click chemistry reactions such as CuAAC and SPAAC, while the carboxyl group allows coupling with amines for amide bond formation. This bifunctional reagent is widely applied in bioconjugation, drug delivery, and materials research, supporting the development of multifunctional biomolecules, therapeutic conjugates, and advanced biomedical materials.
