Used in the synthesis of bioactive molecules, particularly in pharmaceuticals targeting central nervous system disorders and anti-inflammatory agents. Serves as an intermediate in the preparation of fluorescent dyes and optical brighteners due to its conjugated structure. Employed in medicinal chemistry for developing novel heterocyclic compounds with potential anticancer and antimicrobial properties. Also utilized in research for constructing benzothiazole-based scaffolds that show promise in treating neurodegenerative diseases.
