Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds and pharmaceuticals. It participates in cycloaddition reactions to form complex ring systems useful in drug development. Also employed in the synthesis of dyes and fluorescent agents due to its electron-deficient aromatic structure. Shows potential in materials science for developing energetic compounds and high-energy-density materials. Its unique fused ring system makes it valuable in research for designing bioactive molecules with antimicrobial or antitumor activity.
