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 medicinal chemistry due to its nitrogen-rich heterocyclic structure, which can enhance binding affinity to biological targets. Also applied in agrochemicals for the design of novel pesticides and herbicides, leveraging its stability and reactivity in molecular design. Additionally, it has been explored in materials science for the development of fluorescent probes and optoelectronic materials owing to its conjugated framework and electron-donating properties.
