- Description
Hydroxy-PEG1-acid sodium salt is a PEG linker with a hydroxyl group and a terminal carboxyl group in sodium salt form. Its hydrophilic PEG spacer increases aqueous solubility, and the hydroxyl group provides a site for further derivatization or replacement with other reactive groups.
The free acid form is unstable because reaction between hydroxyl and carboxylic acid groups can produce polymer. The sodium salt form is stable for storage and shipping. Listed purity is 98%, and the specified storage temperature is -20°C.
