I. [Product Description]
DOX-PEG-COOH is an organic intermediate with a precise molecular structure. It achieves excellent hydrophilicity and biocompatibility through the polyethylene glycol (PEG) chain and is widely used as a functional carrier or catalyst in coupling reactions. Its carboxyl end group provides an efficient activation site for subsequent modification reactions and is a key pharmaceutical intermediate for constructing complex molecular systems.
