I. [Product Description]
OH-PEG-COOtBu (Hydroxy-polyethylene glycol-tert-butyl propionate) is a high-performance organic intermediate with both amphiphilicity and biocompatibility. It is widely used in the fields of polymer material synthesis, nano-carrier preparation, and functional modification. The PEG segment in its structure can regulate the intermolecular force, and the tert-butyl ester group provides an active site for the subsequent deprotection reaction. It is a key functional module for the synthesis of pharmaceutical intermediates and the construction of catalytic systems.
