I. [Product Description]
Biotin-PEG-PAA (Biotin-Polyethylene Glycol-Polyacrylic Acid) is a multifunctional organic intermediate. Through the precise coupling of biotin with the PEG-PAA copolymer, it combines biocompatibility, modifiability, and water solubility. Its PEG segment provides excellent dispersion stability, and the PAA part imparts pH-responsive properties. It is widely used in bioconjugation, nanomaterial synthesis, and the construction of functional carriers, and is a key raw material for the development of pharmaceutical intermediates and the design of polymer catalysts.
