Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its reactive bromomethyl group allows for easy alkylation or coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in the preparation of pyridazine-containing analogs for structure-activity relationship (SAR) studies. Also utilized in agrochemical research for designing novel active ingredients due to its versatile reactivity and ability to form stable carbon-carbon and carbon-nitrogen bonds.
