I. [Product Description]
NPC-PEG-Biotin is a multifunctional organic intermediate that enables efficient bioconjugation through the high reactivity of the nitrophenyl carbonate (NPC) group, while combining the excellent water solubility of polyethylene glycol (PEG) and the high affinity property of biotin. This compound can be used as a pharmaceutical intermediate or a catalyst carrier and is widely applied in the fields of biological labeling, nanomaterial preparation, and molecular probe development.
