Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring high metabolic stability and lipophilicity. Its strong electron-withdrawing groups enhance the reactivity and binding affinity in various heterocyclic compounds. Commonly employed in the production of fungicides, herbicides, and certain specialty polymers where thermal and chemical resistance are required. Also utilized in the research and development of novel organic materials and fluorinated building blocks for medicinal chemistry.
