Used in pharmaceutical synthesis as a key intermediate for histamine H2 receptor antagonists and anti-ulcer drugs. Also employed in the development of metal-organic frameworks (MOFs) due to its ability to coordinate with metal ions through both carboxylic acid and imidazole functional groups. Shows potential in biomedical research for designing enzyme inhibitors and bioactive ligands. Its structural properties make it suitable for use in fluorescent probes and sensors. Additionally, the carboxylic acid group enables its use as a linker in targeted drug delivery systems.
