t-Boc-N-Amido-C1-Azide-PEG-acid, MW 1,000 has three reactive functional groups for bioconjugation. The Boc group can be deprotected under mild acidic conditions to form the free amine. The azide moiety is commonly used for click chemistry with alkyne molecules via CuAAC/SPAAC. The carboxylic acid (-COOH) terminal can be reacted with amine in the presence of activator, such as HATU or EDC. Reagent grade, for research use only.
