I. [Product Description]
Tosyl-PEG-Aspartic acid is a multifunctional organic intermediate that combines the high reactivity of the tosyl group with the excellent solubility of polyethylene glycol (PEG). At the same time, precise functional modification is achieved through the aspartic acid group. This compound can serve as an efficient catalyst carrier or pharmaceutical intermediate, showing unique value in the fields of bioconjugation, polymer material modification, and nanotechnology.
