Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. It serves as a building block for compounds targeting tyrosine kinases involved in tumor growth and signal transduction pathways. Its structure allows for selective modification to enhance binding affinity and pharmacokinetic properties in drug candidates. Also explored in the design of anti-inflammatory and antimicrobial agents due to its heterocyclic scaffold with electron-donating hydroxyl groups and electron-withdrawing chlorine substituent.
