Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of benzimidazole-based drugs which exhibit antiparasitic, antiviral, and anticancer activities. It serves as a building block in medicinal chemistry for constructing biologically active molecules due to its ability to form imine and other functional derivatives. Also employed in the preparation of fluorescent probes and sensors owing to its favorable photophysical properties. Its structural features make it suitable for coordination with metal ions in catalytic applications.
