Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) that require functionalized sulfur-containing moieties. Its keto and thioester groups enable selective reactions in multi-step organic syntheses. Commonly employed in the development of agrochemicals and specialty chemicals due to its reactivity and structural versatility. Suitable for use in research settings for building complex molecules through nucleophilic addition or condensation reactions.
