I. [Product Description]
Br-PEG-PAA (Bromide-Polyethylene Glycol-Polyacrylic Acid) is a multifunctional organic intermediate that combines the high reactivity of bromides, the excellent water solubility of PEG, and the carboxylic acid functional groups of PAA. It can serve as an efficient catalyst carrier or a core module for the synthesis of pharmaceutical intermediates. Its block structure provides precise molecular design flexibility and is suitable for the construction of complex polymer systems.
