Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated and chlorinated heterocyclic compounds with biological activity. Its aldehyde functionality allows for versatile chemical transformations, making it valuable in constructing complex molecules for drug discovery. Commonly employed in the preparation of kinase inhibitors and antiviral agents due to its ability to enhance metabolic stability and binding affinity. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
