Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of biologically active compounds. Its reactive sulfonyl chloride group allows for easy attachment to various nucleophiles, enabling the construction of sulfonamide derivatives, which are common motifs in drug molecules. The cyanocyclopropyl moiety adds structural rigidity and metabolic stability, making it valuable in medicinal chemistry for optimizing pharmacokinetic properties. It is also employed in agrochemical research for designing novel pesticides and herbicides due to its ability to mimic bioactive structures.
