Used 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 for constructing indazole-based bioactive molecules. Its aldehyde and bromo functional groups allow for selective modifications, enabling the creation of diverse compound libraries for drug discovery. Commonly employed in cross-coupling reactions and condensation processes to form more complex heterocyclic systems with potential anti-inflammatory, antiviral, or antitumor activities.
