Used in pharmaceutical research as a key intermediate in the synthesis of proton pump inhibitors (PPIs), particularly for developing anti-ulcer drugs. Its structure supports the inhibition of gastric acid secretion by targeting H+/K+ ATPase in the stomach lining. Commonly employed in the production of proton pump inhibitor derivatives due to its ability to enhance metabolic stability and bioavailability. Also utilized in the development of novel drug candidates for treating gastroesophageal reflux disease (GERD) and other acid-related disorders.
