I. [Product Description]
SAS-PEG-Biotin (Alkyl Sulfonate-Polyethylene Glycol-Biotin) is a multifunctional organic intermediate with both high reactivity and specific binding ability of biotin. The sulfonic acid group in its molecular structure endows it with excellent solubility, and the PEG segment provides controllable molecular weight and space-hindrance adjustment characteristics. It can be used as a pharmaceutical intermediate or a catalyst carrier, and is widely applied in the fields of bioconjugation and functional material development.
