Used as a fluorescent probe in analytical chemistry due to its strong emission properties when interacting with metal ions or protons. Commonly applied in the development of chemosensors for detecting cations such as zinc, copper, and aluminum in environmental and biological samples. Its aldehyde and amine functional groups allow for easy modification to create Schiff bases, which are effective in molecular recognition and sensing applications. Also utilized in the synthesis of heterocyclic compounds and pharmaceutical intermediates where fluorescence tracking is beneficial. Shows potential in bioimaging due to its ability to cross cell membranes and emit detectable signals in cellular environments.
