Azido-PEG-OH

Azido-PEG-OH is a heterobifunctional PEG reagent featuring an azide group for click chemistry conjugation and a hydroxyl group for further modification. The hydroxyl terminus can be functionalized or serve as a hydrophilic spacer, while the azide enables efficient cycloaddition with alkynes. These reagents are ideal for bioconjugation, polymer synthesis, and surface modification applications.
