N-(2-Cyano-2-propyl)-2-methylpropanamide (CAS 84213-57-0) has a molecular formula of C?H??N?O and molecular weight 168.24 g/mol, with a cyano group on the 2-propyl moiety and a 2-methylpropanamide group attached to the nitrogen. As an amide-containing nitrile, it serves as a precursor in polymer synthesis (e.g., controlled radical polymerization initiators). Store sealed in a cool, dry place to avoid moisture-induced hydrolysis, ensuring reactivity.
