I. [Product Introduction]
Br-PEG-ASP (Bromide-Polyethylene Glycol-Aspartic Acid) is a multifunctional organic intermediate that combines the high reactivity of bromides with the excellent biocompatibility of polyethylene glycol (PEG). It is suitable for coupling reactions, polymer material synthesis, and the construction of catalyst carriers. Its aspartic acid (ASP) functional group can provide directional modification sites and has important application value in the fields of pharmaceutical intermediate development and functionalized nanomaterials.
