Used as a key 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 smooth muscle in blood vessels. The compound's dihydropyridine core is essential for biological activity, enabling selective action on vascular calcium channels. It is also employed in research settings to develop new cardiovascular agents and to study structure-activity relationships in dihydropyridine derivatives.
