Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective enzyme inhibitors. Its structure allows for facile modification in heterocyclic chemistry, making it valuable in creating bioactive molecules. Commonly employed in the preparation of sulfone-containing pyridine derivatives, which show activity in neurological and anti-inflammatory research. Also utilized in agrochemicals for designing novel pesticides with improved metabolic stability. Its allyl sulfonyl group enables efficient cross-coupling reactions, enhancing its utility in medicinal chemistry and process development.
