Used as an organozinc reagent in cross-coupling reactions, particularly in palladium-catalyzed reactions such as Negishi coupling. It enables the formation of carbon-carbon bonds by transferring the 3-cyanobenzyl group to aryl or vinyl halides, making it valuable in the synthesis of complex organic molecules, especially in pharmaceutical and agrochemical research. The presence of the cyano group allows for further functionalization, adding versatility in multi-step synthetic pathways. Its solution form facilitates handling and precise dosing in laboratory-scale reactions. As an air- and moisture-sensitive reagent, it should be handled under inert atmosphere, such as nitrogen, to ensure stability and optimal performance.
