Used primarily as an intermediate in the synthesis of calcium channel blockers, this compound plays a key role in the development of pharmaceuticals for cardiovascular diseases. It is especially valuable in the production of dihydropyridine-based drugs that help manage hypertension and angina by relaxing smooth muscle in blood vessels. Due to its substituted phenyl and dihydropyridine structure, it contributes to high receptor selectivity and potency in final drug formulations. Its ester functionality also allows for further chemical modifications, making it a versatile building block in medicinal chemistry.
