Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its coumarin backbone and functional groups that enhance light absorption and emission. Employed in research for developing sensors that detect metal ions, especially aluminum and zinc, in environmental and biological samples. Shows potential in pharmaceutical studies for antioxidant and anti-inflammatory activity, supporting its exploration in drug design. Also utilized in the preparation of bioactive molecules and heterocyclic compounds for medicinal chemistry applications.
