Used in the synthesis of pharmaceuticals, particularly in the production of antihistamines, vasodilators, anti-inflammatory drugs, antibacterials, and antivirals. Acts as a building block in the development of drugs that improve blood circulation and treat cardiovascular conditions, especially those with heterocyclic structures that enhance biological target binding.

Also serves as an intermediate in the manufacture of dyes, photographic chemicals, and fluorescent compounds, which absorb light at specific wavelengths useful in chemical analysis and detection.

Employed in research laboratories as a reagent for detecting carbonyl compounds due to its ability to form colored derivatives. Additionally, used as a ligand in forming coordination compounds with transition metals, with potential applications as catalysts or new materials in molecular electronics.

Its derivatives are explored for potential antimicrobial and antiviral properties.
