Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nonsteroidal anti-inflammatory drugs (NSAIDs) and other fluorinated bioactive compounds. Its aldehyde and ester functional groups allow for versatile chemical transformations, enabling the construction of complex molecular structures. Commonly employed in condensation reactions and cyclization processes to form heterocyclic rings found in active drug ingredients. Also utilized in agrochemical research for developing new herbicides and plant growth regulators due to its halogenated aromatic backbone, which enhances metabolic stability and target specificity.
