Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its electron-deficient aromatic structure makes it suitable for nucleophilic substitution reactions, enabling the construction of more complex heterocyclic systems. Commonly employed in the preparation of fluorescent dyes and optical brighteners due to its ability to participate in conjugated systems with desirable photophysical properties. Also investigated for use in materials science, especially in the design of electron-transport materials for OLEDs and other optoelectronic devices.
