I. [Product Description]
Tosyl-PEG-OH is a high-purity organic intermediate that combines the high reactivity of the tosyl group with the excellent solubility and flexibility of polyethylene glycol (PEG). It is widely used in the synthesis of pharmaceutical intermediates and the preparation of catalyst supports. The hydroxyl end enables targeted functional modification, providing a key connection site for the development of biocompatible materials.
