I. [Product Introduction]
Biotin-PEG-NPC is a multifunctional organic intermediate that combines the high affinity of biotin with the steric hindrance adjustment properties of the PEG chain. It is widely used in bioconjugation reactions and the development of drug delivery systems. The terminal nitrobenzyl carbonate (NPC) active group can react efficiently with amino groups, making it suitable for constructing stable catalyst carriers or labeled probes. It is a key linking molecule in the field of pharmaceutical intermediate synthesis.
