Widely used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of calcium channel blockers used for treating cardiovascular diseases. It serves as a building block in the production of active pharmaceutical ingredients (APIs) due to its reactive ester and halogen functionalities, which allow for further chemical modifications. Commonly employed in the preparation of nicotinic acid derivatives with potential antihypertensive and antiarrhythmic properties. Also utilized in agrochemical research for developing novel pesticides and plant growth regulators. Its structural features make it valuable in medicinal chemistry for structure-activity relationship (SAR) studies.
