Used as a fluorescent probe in biochemical and analytical applications due to its strong emission under UV light. Its hydroxyl and acetamido groups allow for hydrogen bonding and interaction with biomolecules, making it suitable for studying protein-ligand interactions and enzyme activity. Also employed in the synthesis of dyes and optical brighteners for textiles and paper, where it contributes to light absorption and emission in the visible range. Its stability and solubility in polar organic solvents support use in imaging and labeling techniques.
