Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals. Its structure supports the development of bioactive molecules, particularly in creating herbicides and fungicides due to the presence of chlorinated aromatic rings which enhance stability and target specificity. Also employed in research settings for developing novel organic compounds with potential antimicrobial or insecticidal properties. The aldehyde functional group allows for easy modification, making it valuable in building more complex molecules through condensation or reduction reactions.
