I. [Product Description]
DOX-hyd-PEG-FA is a functionalized polyethylene glycol derivative that connects doxorubicin and folic acid through a hydrazone bond. As a high-performance organic intermediate, it is suitable for constructing targeted nano drug delivery systems. The pH-sensitive hydrazone bond and the FA targeting group in its structure endow it with the precise controlled-release characteristics as a pharmaceutical intermediate. Meanwhile, the PEG segment provides excellent water solubility and biocompatibility, and shows high-efficiency stability in catalytic coupling reactions.
