Used primarily as an intermediate in the synthesis of proton pump inhibitors (PPIs), this compound plays a key role in the development of medications that reduce stomach acid production. It is involved in the preparation of drugs used to treat gastroesophageal reflux disease (GERD), peptic ulcers, and other acid-related gastrointestinal disorders. Due to its reactive functional groups, it enables the construction of complex heterocyclic drug molecules through selective chemical transformations. Its stability and reactivity profile make it suitable for industrial-scale pharmaceutical manufacturing processes.
