Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its reactive aldehyde group and halogenated aromatic structure, enabling coupling reactions and heterocycle formation. Commonly employed in the preparation of bioactive molecules targeting inflammatory diseases and neurological disorders. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and selectivity. Its structural features make it valuable in high-throughput screening and structure-activity relationship (SAR) studies.
