Description

Biotin-PEG2-iodide allows for the applications in bioconjugation, surface functionalization, and targeted drug delivery systems. Biotin, also known as vitamin B7 or vitamin H, is a water-soluble B vitamin. It consists of a bicyclic ring structure with a ureido ring attached at one end. Biotin is known for its high affinity for avidin and streptavidin proteins, making it widely used in biological applications for labeling and detection purposes. PEG is often used as a linker in bioconjugation reactions due to its biocompatibility and ability to enhance solubility and stability of conjugates. Iodide is a halide ion (I-) which serves as the leaving group in the synthesis of Biotin-PEG2-iodide. In the molecule, iodide is typically attached to the PEG2 linker via a covalent bond.
