Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and central nervous system (CNS) active agents. Its structure supports the formation of heterocyclic compounds with biological activity, making it valuable in medicinal chemistry for drug discovery. It is also employed in the preparation of selective serotonin reuptake inhibitors (SSRIs) and related antidepressant molecules. Additionally, it serves as a building block in the creation of fused thiophene derivatives for use in organic electronics and research due to its electron-rich framework.
