Propargyl-PEG3-t-butyl ester（Cat No.:I014608）is a compound consisting of a propargyl group, a polyethylene glycol (PEG) linker with three ethylene glycol units (PEG3), and a t-butyl ester group. The propargyl group can undergo click chemistry reactions, such as the copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it useful for conjugation in chemical biology and drug delivery applications. The PEG3 segment enhances water solubility and stability, while the t-butyl ester group provides protection during synthesis and can be cleaved under specific conditions. This compound is often employed in the development of bioconjugates, targeted therapies, and molecular imaging agents.
