Used as a fluorescent probe in biochemical assays due to its strong emission properties, particularly in detecting metal ions such as aluminum and zinc in environmental and biological samples. Its structure allows for selective binding and signal enhancement in the presence of specific cations. Also investigated for antioxidant activity in pharmacological studies, showing potential in mitigating oxidative stress in cellular models. Employed in the synthesis of more complex coumarin derivatives for use in dyes and optical brighteners in industrial applications.
