I. [Product Description]
Aminooxy-PEG-Estrogen is a high-purity organic intermediate that achieves efficient chemical modification through the precise coupling of aminooxy groups and PEG chains. Its molecular structure combines the water solubility of PEG and the reactivity of estrogen derivatives. It is suitable for the synthesis of pharmaceutical intermediates and bioconjugation catalytic reactions. The molecular weight can be customized according to requirements to ensure compatibility with the target system.
