Used as a fluorescent probe in biochemical assays due to its strong emission properties under UV light. Its structure allows for selective binding to specific enzymes, making it useful in monitoring enzymatic activity, particularly in studies involving esterases and lipases. Also employed in the development of sensors for metal ion detection, especially for aluminum and zinc in environmental and biological samples. Shows potential in photodynamic therapy research owing to its ability to generate reactive oxygen species when exposed to light. Additionally, it serves as an intermediate in the synthesis of more complex coumarin-based derivatives with pharmaceutical applications.
