Used primarily as an intermediate in the synthesis of calcium channel blockers, particularly in the production of nifedipine-type drugs. These medications are widely prescribed for the treatment of hypertension and angina due to their ability to relax vascular smooth muscle. The compound’s structure allows for efficient photochemical cyclization, making it valuable in the preparation of dihydropyridine derivatives. It is also employed in research settings to develop new cardiovascular agents and to study structure-activity relationships in pyridine-based pharmaceuticals.
