Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of proton pump inhibitors like omeprazole and esomeprazole, which are widely prescribed for treating gastric acid-related disorders such as GERD and peptic ulcers. Its structure allows for selective reactivity, making it valuable in forming active pharmaceutical ingredients. Also employed in agrochemicals for developing herbicides and pesticides due to its stability and reactivity in coupling reactions. Commonly utilized in research and development for creating new pyridine-based compounds with potential biological activity.
