I. [Product Description]
Biotin-PEG-NH2 is a multifunctional organic intermediate. Through the precise coupling of biotin with amino functional groups, it is widely used in bioconjugation reactions and material surface modification. Its core value lies in the tunable molecular weight design of the PEG chain (2000-5000 Da), which has excellent hydrophilicity and biocompatibility. It can be used as an efficient catalyst carrier or pharmaceutical intermediate.

II. [Product Details]
