Aminooxy-PEG-acid is a heterobifunctional PEG reagent featuring an aminooxy group for oxime ligation and a terminal carboxyl for conjugation. Synthesized via controlled polymerization, it typically follows the formula H2N-PEG-COOH with variable chain lengths (n). Specific CAS numbers vary by molecular weight.
Store at -20°C under inert atmosphere to prevent hydrolysis. Avoid contact with strong oxidizers. Not approved for direct human administration; strictly for research use only in synthesis workflows.
