Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective substitution at reactive sites, enabling the construction of complex bioactive molecules. Commonly employed in medicinal chemistry for optimizing drug candidates targeting tyrosine kinase and other enzyme pathways. Also utilized in agrochemical research for designing novel pesticides due to its stable heterocyclic core and halogenation pattern that enhances biological activity.
