Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated active pharmaceutical ingredients (APIs) where the bromo and fluoro substituents allow for selective cross-coupling reactions. Its aldehyde functionality enables condensation and nucleophilic addition reactions, making it valuable in constructing complex organic molecules. Commonly employed in agrochemical research for designing novel pesticides and herbicides due to the enhanced stability and bioactivity imparted by halogen atoms. Also utilized in materials science for creating specialty organic semiconductors and liquid crystals, where halogen substitution influences electronic properties and molecular packing.
