Widely used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its structure allows for selective functionalization, making it valuable in constructing complex molecules. Commonly employed in the development of herbicides and fungicides due to the presence of halogen and trifluoromethyl groups, which enhance biological activity and stability. Also utilized in the preparation of dyes and fluorescent compounds, where the aldehyde group facilitates coupling reactions. Its electron-withdrawing substituents improve reactivity in nucleophilic addition and condensation reactions, useful in fine chemical manufacturing.
