Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of bioactive molecules due to its ability to form stable complexes with metal ions, making it valuable in catalysis and medicinal chemistry. Also employed in the design of organic semiconductors and luminescent materials owing to its conjugated structure and electron-donating properties. Its derivatives are explored in agrochemicals for improved crop protection agents.
