Used in organic synthesis as an intermediate for pharmaceuticals and biologically active compounds. Serves as a building block in the development of imidazole-based drugs, which may exhibit antimicrobial, antifungal, or anticancer properties. Also applied in the preparation of fluorescent probes and sensors due to its aldehyde functional group, enabling derivatization for detection of biomolecules. Its aromatic and heterocyclic structure makes it suitable for coordination with metal ions in catalysis or material science research.
