Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure enables selective binding to enzyme active sites, making it valuable in drug discovery. Also employed in agrochemical research for designing novel pesticides with improved efficacy and environmental safety. Commonly utilized in organic synthesis to build complex heterocyclic systems due to its reactive aldehyde group and halogen substituent, which allow for further functionalization through cross-coupling reactions.
