Tos-PEG6-acid Chemical Properties, Uses, Production

Uses

Tos-PEG6-acid 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. HATU) to form a stable amide bond.
