I. [Product Description]
HZ-PEG-OPSS is a multifunctional organic intermediate with the reactivity of both hydrazide groups (HZ) and ortho-pyridyl disulfide (OPSS). It is suitable for biological conjugation, nanomaterial synthesis, and polymer modification fields. Its core value lies in the adjustable molecular weight of the PEG segment and excellent biocompatibility. It can be used as an efficient cross-linking agent or catalyst carrier, and is widely used in the development of pharmaceutical intermediates and the functionalization of material surfaces.

II. [Product Details]
