Tosylate-PEG-OH

Price range: $200.00 through $1,200.00

Tosylate-PEG-OH (Ts-PEG-OH) is a heterobifunctional polyethylene glycol derivative containing a tosylate (p-toluenesulfonate) group at one terminus and a hydroxyl (OH) group at the other. The tosylate group serves as an excellent leaving group for nucleophilic substitution reactions, enabling the synthesis of a wide range of functional PEG derivatives. Tosylate-PEG-OH is widely used as a versatile PEG intermediate in polymer chemistry, bioconjugation, drug delivery, and materials science research.

Tosylate-PEG-OH structure

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.
