I. [Product Description]
COOH-PEG-OtBu is a polyethylene glycol derivative containing a carboxyl group and a tert-butyl protecting group. As a high-performance organic intermediate, it is widely used in the synthesis and modification of pharmaceutical intermediates, and can also serve as a functional carrier in catalytic reactions. The PEG segment in its structure provides excellent solubility and biocompatibility, and the tert-butyl protecting group effectively enhances the reaction selectivity, making it suitable for the construction of complex coupling systems.
