I. [Product Description]
SAS-PEG-SPDP is a multifunctional organic intermediate. Through the precise coupling of alkyl sulfonate (SAS), polyethylene glycol (PEG), and N-hydroxysuccinimide ester of 3-(2-pyridyldithio) propionic acid (SPDP), it combines excellent biocompatibility with controllable reactivity. This compound can be used as an efficient catalyst or linker, and is widely used in the fields of bioconjugation, polymer material modification, and nanocarrier construction. Its modular structure supports flexible customized design.
