Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly those targeting tyrosine kinases involved in cancer cell proliferation. Shows potential in developing treatments for solid tumors due to its ability to cross cell membranes and bind selectively to ATP-binding sites in target enzymes. Also explored for antiviral applications due to structural similarity to known viral polymerase inhibitors. Commonly employed in structure-activity relationship (SAR) studies to optimize potency and reduce off-target effects in drug candidates.
