Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and insecticides due to its halogenated and electron-withdrawing functional groups. Its aldehyde functionality allows for easy modification in multi-step organic syntheses, enabling the formation of more complex molecules. Commonly employed in the preparation of nicotinic receptor ligands and other bioactive compounds. Also utilized in research settings for building fluorinated heterocyclic systems, which are valued for their metabolic stability and enhanced lipophilicity in drug design.
