I. [Product Description]
VA-PEG-Biotin (Valeric acid-Polyethylene glycol-Biotin) is a multifunctional organic intermediate. It connects the valeric acid and biotin groups through a precisely designed PEG chain, combining excellent hydrophilicity and targeted binding ability. This compound can be used as a pharmaceutical intermediate for the construction of bioconjugation systems or as a molecular bridging tool in catalytic reactions, significantly enhancing the stability and selectivity of the reaction system.
