Used primarily in organic synthesis as an alkylating agent, it facilitates the introduction of nonyl groups into various compounds. It is particularly valuable in the preparation of surfactants, lubricants, and other specialty chemicals. The stabilization with copper chips prevents unwanted decomposition, ensuring consistent performance in reactions. Additionally, it serves as a key intermediate in the production of pharmaceuticals and agrochemicals, where precise alkylation is critical. Its application extends to research and development, aiding in the study of reaction mechanisms and the synthesis of complex organic molecules.
