BCN-PEG2-NHS ester CAS:2243565-12-8 is a bifunctional PEG reagent consisting of a BCN (bicyclononyne) group, a PEG2 spacer, and an NHS ester. BCN, used in copper-free click chemistry, reacts with azides to form triazole linkages. PEG2 refers to a polyethylene glycol molecule with two repeating units, known for its biocompatibility. The NHS ester group forms stable amide bonds with primary amines, useful in coupling reactions. This compound is employed in bioconjugation, drug delivery, and material science.
