I. [Product Introduction]
NH2-PEG-COOH is a bifunctional polyethylene glycol derivative with both amino and carboxyl reactive groups. It can serve as an efficient organic intermediate or pharmaceutical intermediate and is widely used in bioconjugation, material modification, and catalyst support construction. The adjustable PEG chain length endows the product with excellent hydrophilicity, biocompatibility, and controllable molecular spacing, making it suitable for the design of complex functional molecules.
