Hydroxy-PEG4-methyl ester linker contains a hydroxyl group and a methyl ester. The PEG spacer increases the aqueous solubility of the resulting compound. The hydroxyl group can be derivatized to other reactive functional groups for conjugation. Methyl ester can be hydrolyzed under strong basic condition to form a free acid, which can under amide coupling with amine bearing biomolecules.
Hydroxy-PEG4-methyl ester is a chemical compound that is a methyl ester of hydroxy-polyethylene glycol (PEG). It is used in various biotechnological and pharmaceutical applications, such as providing a hydrophobic coating to drug-delivery systems and as a solvent in some organic reactions.
