Methoxy PEG Thioctic Acid (MW 2000) is a bifunctional PEG derivative featuring a thiol-reactive lipoic acid moiety. It serves as a critical linker for conjugating drugs to PEG chains via disulfide bonds, enabling controlled release in reducing intracellular environments. Molecular Formula: CxHyNzOwSv (varies with PEG length). CAS No.: Typically unassigned specific number due to polydispersity.
Store under inert atmosphere at -20°C to prevent oxidation of the thiol group. Avoid contact with strong oxidizers. Use only in GMP-compliant facilities; not approved for direct clinical use without formulation validation.
