Description
General Description
Tosylate-PEG-OH is a reactive PEG building block designed for the preparation of amine-, thiol-, azide-, alkyne-, carboxyl-, and other functionalized PEG derivatives. The terminal tosylate group readily undergoes substitution reactions with nucleophiles such as amines, thiols, azides, and alcohols, while the hydroxyl group remains available for further modification.
Due to its high reactivity and synthetic versatility, Tosylate-PEG-OH is commonly employed in the preparation of heterobifunctional PEG linkers, PEGylation reagents, drug delivery materials, and advanced polymer conjugates.
