Used as a key intermediate in the synthesis of potent antiviral and antibacterial agents, particularly in the development of drugs targeting hepatitis C and other RNA viruses. Its structure enables effective binding to viral enzymes, making it valuable in medicinal chemistry for designing inhibitors. Also employed in the preparation of kinase inhibitors for cancer therapy due to its ability to modulate cellular signaling pathways. Commonly utilized in combinatorial chemistry and high-throughput screening for lead optimization in drug discovery programs.
