Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceutical research targeting cancer therapies. Its structure enables selective modification for developing compounds with high potency against specific protein kinases involved in tumor growth. Commonly employed in medicinal chemistry for constructing pyrrolopyrimidine-based drug candidates, especially in EGFR and JAK kinase inhibitor programs. Also utilized in agrochemical research for designing novel bioactive molecules due to its favorable reactivity and scaffold diversity.
