Used in organic synthesis as a building block for more complex molecules, particularly in pharmaceuticals and agrochemicals. Its structure allows for the introduction of fluorine atoms into target compounds, which can enhance biological activity and metabolic stability. It is also utilized in the development of fluorescent dyes and probes for biochemical research, due to its naphthalene core and fluorophore properties. Additionally, it serves as an intermediate in the production of materials with specific optical or electronic properties.
