Used primarily as an intermediate in the production of nylon-6, 6-aminocapronitrile plays a key role in polymer manufacturing. It is converted into 6-aminocaproic acid, which then forms caprolactam—the monomer essential for nylon-6 synthesis. This makes it valuable in textiles, plastics, and synthetic fiber industries. Additionally, it serves as a building block in organic synthesis for pharmaceuticals and fine chemicals, where its amine and nitrile functional groups allow for diverse chemical transformations. Its reactivity supports the development of specialty amines and heterocyclic compounds used in agrochemicals and medicinal chemistry.
