Used as a fluorescent probe in biochemical assays due to its strong fluorescence properties, particularly in detecting metal ions such as aluminum and iron in environmental and biological samples. Its hydroxyl and carboxylic acid groups enable chelation with metal ions, making it valuable in sensor development. Also investigated for its antioxidant activity in pharmaceutical research, where it serves as a scaffold for designing compounds with radical-scavenging effects. Applied in studies related to oxidative stress due to its ability to interact with reactive oxygen species.
