Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of kinase inhibitors and anticancer agents. Its bromomethyl functional group allows for easy alkylation or coupling reactions, making it valuable in medicinal chemistry for building more complex drug-like molecules. Commonly employed in the preparation of quinazoline-based derivatives that target epidermal growth factor receptor (EGFR) pathways. Also utilized in research settings to develop fluorescent probes or labeled compounds for biochemical assays due to its reactive handle and stable heterocyclic core.
