I. [Product Introduction]
Biotin-PEG-SAS (Biotin-Polyethylene Glycol-Succinimidyl Succinate) is a multifunctional organic intermediate that combines the high affinity characteristics of biotin with the biocompatibility of the PEG chain. It is suitable for the fields of bioconjugation, nanomaterial modification, and polymer synthesis. Its succinimidyl ester group (SAS) can act as an efficient catalyst to achieve highly specific coupling with amino groups, and is widely used in the development of pharmaceutical intermediates and the preparation of functional materials.
