Used in research as a fluorescent probe due to its strong emission properties, particularly in studying protein interactions and conformational changes in biological systems. Its structure allows for intercalation into nucleic acids, making it useful in DNA and RNA detection assays. Also investigated for its potential as a photosensitizer in photodynamic therapy, where it can generate reactive oxygen species under light exposure to target cancer cells. Additionally, serves as a building block in the synthesis of more complex indole-based pharmaceuticals with possible neuroactive and anticancer activities.
