Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of biologically active compounds and heterocyclic molecules. Its cyclic sulfone structure enhances stability and reactivity, making it valuable in medicinal chemistry for constructing complex drug scaffolds. It is also employed in the preparation of functionalized pyrrolidines and other nitrogen-containing rings through ring-opening or ring-expansion reactions. Additionally, it serves as a building block in agrochemicals and specialty materials due to its unique polarity and conformational properties.
