I. [Product Description]
Chloride-PEG-ASP (Chloride-Polyethylene Glycol-Aspartic Acid) is a multifunctional organic intermediate. Through PEG modification, the water solubility and biocompatibility of aspartic acid derivatives are significantly improved. It is widely used in the fields of pharmaceutical intermediate preparation and polymer material synthesis. Its unique structural design allows it to serve as an efficient catalyst carrier or reaction medium, meeting the requirements of complex synthesis systems.
