Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. It plays a role in targeting protein kinases involved in cell signaling pathways, showing potential in the treatment of various tumors. Its structure allows for strong hydrogen bonding and improved solubility, enhancing drug efficacy and bioavailability in pharmaceutical formulations. Also utilized in research for designing selective inhibitors of nitric oxide synthase (NOS) due to its ability to mimic arginine substrates.
