Used primarily as an intermediate in organic synthesis, particularly in the pharmaceutical industry for constructing complex cyclic structures. Its nitrile group allows for versatile functional group transformations, such as reduction to amines or hydrolysis to carboxylic acids, enabling the development of bioactive molecules. Frequently employed in the preparation of cycloheptane-based analogs for drug discovery, especially in central nervous system agents and receptor modulators. Also utilized in the synthesis of specialty agrochemicals and fine chemicals where a seven-membered aliphatic ring system is required.
