- Description
Tos-PEG4-CH2CH2COOtBu is a functional PEG linker combining a tosyl leaving group with a t-butyl-protected ester. The tosyl group supports nucleophilic substitution, while mild acidic deprotection of the ester yields a free carboxyl group. Its PEG4 spacer promotes aqueous solubility for chemical and biological applications. These functionalities support bioconjugation and organic synthesis requiring subsequent modification at either end of the linker.
