Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its rigid heterocyclic structure and electron-withdrawing nitro group. Its thione functionality allows for metal coordination, making it useful in the development of chemosensors for detecting heavy metal ions in environmental samples. Also employed in the preparation of bioactive compounds, particularly in medicinal chemistry for designing antimicrobial and antitumor agents. The compound’s photochemical stability enhances its suitability in light-emitting materials and organic semiconductors.
