Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its aldehyde and methoxy functional groups allow for selective reactions, making it valuable in constructing complex heterocyclic compounds. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to modify molecular polarity and binding affinity. Also utilized in agrochemical research for designing novel active ingredients with improved stability and efficacy.
