Used as a key intermediate in organic synthesis, particularly in the preparation of nitrogen-containing heterocyclic compounds. It participates in cycloaddition reactions to form complex aromatic systems, which are valuable in pharmaceuticals and agrochemicals. Its electron-deficient structure makes it suitable for use in materials science, especially in the development of organic semiconductors and conductive polymers. Also employed in the synthesis of dyes and pigments due to its ability to form stable conjugated systems.
