I. [Product Description]
COOH-PEG-CH2CH2COOtBu is a multi-functional organic intermediate that combines a carboxylic acid active group and a tert-butyl ester protecting group. It enables precise molecular weight control through a customizable PEG chain. Its amphiphilic structure endows it with excellent solubility and biocompatibility, and it is widely used in the fields of polymer material synthesis, bioconjugation, and catalyst loading. It is the core module for constructing functional materials.
