Used primarily 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 vascular smooth muscle. The compound’s structure allows for efficient nitrophenyl group reduction and subsequent functionalization, making it valuable in pharmaceutical manufacturing. Its high selectivity and yield in coupling reactions contribute to cost-effective and scalable synthesis routes in the development of cardiovascular therapeutics.
