Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its reactivity allows for the introduction of sulfonyl groups into organic molecules, facilitating the formation of sulfonamides—key structural motifs in many bioactive compounds. Commonly employed in the development of herbicides and fungicides due to its ability to enhance molecular stability and binding affinity. Also utilized in medicinal chemistry for constructing enzyme inhibitors, particularly in kinase-targeted drug discovery. The presence of both cyano and fluoro groups enables further functionalization and improves pharmacokinetic properties in lead compounds.
