Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It is also employed in agrochemicals to enhance the stability and bioavailability of active ingredients. Its rigid cyclopropane ring and heteroaromatic system make it valuable in medicinal chemistry for improving metabolic stability and target binding affinity. Additionally, it serves as a building block in the preparation of fluorescent probes and optoelectronic materials due to its electron-withdrawing nitrile group and conjugated structure.
