I. [Product Description]
COOH-PEG-NH₂ is a bifunctional polyethylene glycol derivative with both carboxyl and amino reactivity. It is widely used as a high-performance organic intermediate in bioconjugation, polymer material modification, and catalytic system construction. Its PEG segment with adjustable molecular weight provides excellent water solubility and biocompatibility, and it is a key linker for the development of pharmaceutical intermediates and the synthesis of functionalized nanomaterials.

II. [Product Details]
