I. [Product Description]
DOX-PEG-Tosyl is a high-purity organic intermediate developed based on the core structure of doxorubicin, which enables precise coupling reactions through the activation of tosyl groups. This compound combines the excellent water solubility and steric hindrance effect of polyethylene glycol (PEG) and can be used as a pharmaceutical intermediate to construct functional polymer systems. Its modular design is particularly suitable for catalytic reaction systems that require controllable modification.
