Ɑ-Methoxy-ω-Succinamic Acid PEG

This methoxy capped PEG carboxylic acid has a succinic acid (C4) group atteached via an amide linkage. After activation with coupling reagents (e.g. NHS, DCC) it is useful for pegylation of amine substrates (forming an amide bond) or for the formation of hydrolyzable esters and thioesters.
