Used primarily in research settings as a fluorescent probe due to its strong emission properties when excited. Its structure allows for interaction with biomolecules, making it useful in studying protein binding and conformational changes. Also investigated for its potential as a sensor in detecting metal ions in environmental and biological samples. Shows promise in photodynamic therapy research because of its ability to generate reactive oxygen species under light exposure. Additionally, its indole-based framework supports exploration in developing novel anti-inflammatory and anticancer agents.
