Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its halogenated structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex molecules. It is also employed in the preparation of bioactive quinoline derivatives with potential antimicrobial and anti-inflammatory properties. Due to the presence of reactive bromo and chloro groups, it serves as a versatile building block in Suzuki, Stille, and Buchwald-Hartwig reactions in drug discovery research.
