t-Boc-aminooxy-PEG-Propargyl is a functionalized polyethylene glycol (PEG) molecule that contains several important functional groups. The t-Boc group serves as a protecting group for the amino group, allowing for selective deprotection and subsequent modification. The aminooxy group is useful for bioconjugation reactions, while the propargyl group allows for click chemistry reactions. These functional groups make t-Boc-aminooxy-PEG-Propargyl a valuable tool in pharmaceutical research and development. It can be used for site-specific conjugation of drugs, as well as for the development of targeted drug delivery systems. Additionally, the click chemistry reaction facilitated by the propargyl group allows for efficient synthesis of complex molecules, making it a useful tool for drug discovery.
