Used as a fluorescent probe in biochemical and analytical applications due to its strong emission properties. It serves in the detection of metal ions, especially aluminum and iron, in environmental and biological samples. Also employed in the synthesis of more complex fluorophores and sensors. Its hydroxyl and carboxylic acid groups allow for easy conjugation to biomolecules, making it useful in labeling proteins and nucleic acids for imaging studies. Additionally, it acts as an intermediate in the preparation of pharmaceuticals and agrochemicals with bioactive properties.
