Used as a key intermediate in the synthesis of calcium channel blockers, particularly in the development of dihydropyridine-based cardiovascular drugs. Its structure allows for selective modulation of L-type calcium channels, making it valuable in creating antihypertensive and antianginal agents. Commonly employed in research settings to design new derivatives with improved pharmacokinetic profiles. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies to enhance potency and reduce side effects in next-generation heart medications.
