Overview

Acid-PEG4-mono-methyl ester is a PEG derivative with a carboxylic acid and methyl ester group. Methyl ester can be hydrolyzed under strong basic condition. The carboxylic acid can be reacted with primary amines in the presence of EDC and DCC to form stable amide bonds. The hydrophilic PEG linker increases the water solubility of the compound in aqueous media.
