I. [Product Description]
Br-PEG-COOH (Bromide-Polyethylene Glycol-Carboxyl) is a multifunctional organic intermediate, possessing both excellent chemical reactivity and biocompatibility. Its bromine group can serve as an anchoring site for highly efficient catalysts, while the carboxyl group provides the ability for directional coupling. It is widely used in the preparation of pharmaceutical intermediates and the surface functional modification of nanomaterials. The introduction of the PEG segment significantly enhances the water solubility and stability of the product.
