Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its aldehyde functional group allows for easy modification and coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic structures. Commonly utilized in research settings to design bioactive molecules with potential anti-inflammatory, antiviral, or antitumor activity. Also employed in the preparation of indazole-based derivatives for structure-activity relationship (SAR) studies.
