Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of dihydropyrimidinone (DHPM) derivatives which exhibit a range of biological activities. Commonly employed in the preparation of calcium channel modulators and antihypertensive agents. Also utilized in agrochemicals for the design of novel pesticides and herbicides due to its structural similarity to bioactive heterocycles. Serves as a building block in combinatorial chemistry and drug discovery for generating compound libraries targeting enzymes and receptors. Its reactivity allows for easy functionalization, making it valuable in the synthesis of fused pyrimidine systems with potential antimicrobial, anti-inflammatory, and anticancer properties.
