Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules due to the presence of multiple reactive sites. The aldehyde group enables condensation reactions, while the bromo and chloro substituents allow for cross-coupling reactions such as Suzuki or Heck reactions, facilitating the construction of complex aromatic structures. Its hydroxy group can participate in hydrogen bonding or be functionalized further, making it valuable in the design of specialty organic compounds, including potential antimicrobial or anti-inflammatory agents. Also employed in the preparation of dyes and functional polymers where halogenated aromatic aldehydes are required.
