Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure allows for selective modification to enhance binding affinity to specific enzyme targets. Commonly employed in pharmaceutical research for optimizing drug candidates targeting protein kinases involved in cell proliferation. Also utilized in the preparation of compounds with antiviral and anti-inflammatory activities. Its chlorine and methyl functional groups facilitate further cross-coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic systems.
