Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting tyrosine kinases involved in cancer cell signaling. Shows potential in developing treatments for solid tumors due to its ability to cross cell membranes efficiently and bind selectively to ATP-binding sites in target enzymes. Also explored for antiviral applications due to structural similarity to purine analogs. Its ethyl and chloro substitutions enhance metabolic stability and bioavailability in preclinical models.
