Used in the synthesis of pharmaceutical intermediates, particularly in the development of antihypertensive and antimicrobial agents. It serves as a key building block in heterocyclic chemistry due to its reactive amino and carbonyl groups, enabling the formation of various fused ring systems. Also employed in the preparation of agrochemicals and dyes, where its structure contributes to enhanced stability and biological activity. Its derivatives show potential in coordination chemistry as ligands for metal ions in catalytic applications.
