Used as a fluorescent probe in biochemical and analytical applications due to its strong emission properties. It serves as a scaffold in the synthesis of more complex coumarin derivatives with potential pharmacological activities, including antioxidant, anti-inflammatory, and antimicrobial effects. Also investigated for its role in metal ion sensing, particularly for detecting aluminum and zinc in environmental and biological samples. Its natural occurrence in some plants makes it relevant in phytochemical studies and natural product research.
