I. [Product Description]
HSA-PEG-Estrogen is a high-purity organic intermediate prepared through the site-specific coupling technology of human serum albumin (HSA) and polyethylene glycol (PEG). It can be used as a pharmaceutical intermediate in bio-conjugation reactions or catalyst carrier systems. Its unique PEG-modified structure significantly enhances water solubility and stability, making it suitable for functional modification requirements in complex chemical environments.
