Tos-PEG5-CH2CO2H

Overview

Tos-PEG5-CH2CO2H is a PEG linker containing a tosyl group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Please contact us for GMP-grade inquiries.
