Azido-PEG24-acid（Cat No.:I045929）is a long-chain polyethylene glycol linker with an azide group at one end and a terminal carboxylic acid at the other, connected through a 24-unit PEG spacer. The extended PEG24 chain provides excellent water solubility, flexibility, and spacing, reducing steric hindrance and enhancing biomolecular interactions. The azide group enables bioorthogonal click chemistry reactions, such as CuAAC or SPAAC, while the carboxyl group supports amide coupling with amines. This bifunctional reagent is valuable in drug delivery, bioconjugation, and materials science for designing multifunctional molecules, targeted therapeutics, and advanced biomaterials.
