I. [Product Description]
Tosylate-PEG-NH2 is a versatile organic intermediate that combines the high reactivity of tosylate with the biocompatibility of the PEG chain. It is widely used in the synthesis of pharmaceutical intermediates and the modification of polymer materials. The terminal amino group can efficiently participate in coupling reactions, while the PEG segment can regulate the hydrophilicity of the molecule, making it a core component in the construction of catalytic systems and the development of functional materials.
