Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of proton pump inhibitors (PPIs) like omeprazole and related compounds. These drugs are widely prescribed for the treatment of gastric acid-related disorders, including gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome. The amine group and pyridine ring in its structure allow for functionalization in multi-step synthetic routes, enabling the formation of active drug substances. Its reactivity and stability make it suitable for use in industrial-scale manufacturing under controlled conditions.
