I. [Product Description]
Biotin-PEG-Br is a multifunctional organic intermediate. Its structure integrates the high-affinity properties of biotin, the high-efficiency reactivity of bromide, and the controllable water solubility and biocompatibility of the PEG chain. It is widely used in bioconjugation, polymer synthesis, and catalytic reaction systems. This compound can serve as a pharmaceutical intermediate or cross-linking agent and is of great value in the construction of functional materials and the development of molecular probes.
