I. [Product Description]
Biotin-PEG-STA is a multifunctional organic intermediate synthesized by an efficient coupling technology using biotin, polyethylene glycol (PEG), and stearic acid (STA). It combines the high affinity of biotin, the excellent water solubility of the PEG chain, and the hydrophobic anchoring properties of STA. This compound can be used as a pharmaceutical intermediate for targeted carrier construction or as a surface modifier in catalytic systems, significantly improving the stability and functionalization efficiency of materials.
