N-Boc-hexahydro-1H-azepin-4-one is primarily used in organic synthesis as a key intermediate in the preparation of various pharmaceutical compounds. Its structure, featuring a protected amine group (Boc group) and a ketone, makes it versatile for constructing complex molecules, particularly in the synthesis of nitrogen-containing heterocycles. It is often employed in the development of drug candidates, especially those targeting neurological disorders, due to its ability to serve as a scaffold for bioactive molecules. Additionally, it is utilized in peptide chemistry for modifying amino acid derivatives and in the production of specialty chemicals for research and industrial applications.
