Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with anti-inflammatory and analgesic properties. Its structure allows for selective functionalization, making it valuable in constructing complex organic molecules. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build biaryl systems found in drug candidates. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its halogenated aromatic framework, which enhances bioavailability and target binding. Its aldehyde group enables easy conversion into acids, alcohols, or imines, supporting diverse derivatization pathways in medicinal chemistry.
