I. [Product Description] 
DOX-PEG-HZ is a high-purity organic intermediate that achieves precise coupling function through a hydrazide bond. It can be used as a pharmaceutical intermediate to construct targeted carriers or bioconjugation systems. Its core value lies in the tunability of the PEG segment and the reactivity of the hydrazide group, which is suitable for catalytic coupling reactions and the development of functional materials.
