I. [Product Description]
SAS-PEG-Tyrosine (Alkyl Sulfonate-Polyethylene Glycol-Tyrosine) is a multi-functional organic intermediate that combines high surface activity with biocompatibility. It can be used as a pharmaceutical intermediate for polymer material modification and targeted carrier preparation. The PEG segment in its structure provides excellent hydrophilicity, the alkyl sulfonate group enhances interfacial activity, and the tyrosine residue imparts directional coupling ability. It also exhibits stable carrier characteristics in catalytic reaction systems.
