Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports the formation of bioactive molecules by serving as a building block in medicinal chemistry. Commonly employed in research settings to design compounds with potential anti-inflammatory, antiviral, or antitumor activity. Also utilized in the preparation of fluorescent probes due to its favorable photophysical properties, making it useful in biochemical imaging and assay development.
