Used in pharmaceutical research as a key intermediate in the synthesis of proton pump inhibitors, which are drugs designed to reduce stomach acid production. Its structure supports the development of compounds with high selectivity and potency in treating gastrointestinal disorders such as gastroesophageal reflux disease (GERD) and peptic ulcers. The sulfinyl and oxazole groups contribute to its reactivity and binding properties, making it valuable in optimizing drug efficacy and metabolic stability.
