I. [Product Description] 
Epoxides-PEG-biotin is a versatile organic intermediate that enables efficient cross-linking reactions through epoxide groups. It is suitable for bioconjugation and material surface modification. Its PEG segment significantly enhances water solubility and biocompatibility, and the biotin label facilitates targeted recognition. It is widely used in the construction of catalytic systems and the development of functionalized materials.
