Used primarily in the synthesis of pharmaceutical intermediates, especially in the development of proton pump inhibitors for treating gastrointestinal disorders such as acid reflux and peptic ulcers. Its structure supports the formation of active compounds that inhibit gastric acid secretion. Commonly employed in research settings for designing new nitrogen-containing heterocyclic drugs. Also utilized in medicinal chemistry for optimizing drug stability and bioavailability due to its favorable ring conformation and functional group compatibility.
