I. [Product Description] 
OH-PEG-CH2COOtBu (Hydroxyl-polyethylene glycol-tert-butyl acetate) is a high-purity organic intermediate with excellent biocompatibility and controllable chemical reactivity. It is widely used in the synthesis of pharmaceutical intermediates, the modification of polymer materials, and the surface functionalization of nanocatalysts. The hydroxyl group and tert-butyl ester group at the molecular ends provide a flexible functionalization platform for multi-step coupling reactions.
