Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of imidazole-based drugs with antifungal, anti-inflammatory, and anticancer properties. Its aldehyde functional group allows for easy modification, making it valuable in creating diverse derivatives for drug discovery. Also employed in the preparation of fluorescent dyes and sensors due to its ability to form conjugated systems that exhibit strong emission under UV light. Commonly used in organic synthesis for constructing nitrogen-containing heterocycles and in materials science for designing optoelectronic materials.
