Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. Its structure enables strong binding to specific enzyme targets, enhancing drug efficacy. Commonly employed in research settings to design compounds with improved metabolic stability and selectivity. Also utilized in agrochemicals for creating novel pesticides due to its electron-withdrawing groups that enhance bioactivity. Shows promise in materials science for developing fluorescent probes and optoelectronic materials owing to its rigid aromatic framework and electron-deficient nature.
