I. [Product Description]
Biotin-PEG-OH is a high-purity organic intermediate. Through the precise coupling of biotin and polyethylene glycol (PEG), it is endowed with excellent water solubility and biocompatibility. As a pharmaceutical intermediate, it is widely used in bioconjugation reactions and the construction of molecular probes. Its PEG chain can adjust steric hindrance and enhance stability, making it suitable for the precise modification of complex systems.
