Used as a high-performance fluorescent whitening agent in optical brighteners for specialty polymers and coatings. Its strong electron-withdrawing trifluoromethyl groups enhance photostability and improve compatibility with fluorinated materials. Commonly applied in aerospace, electronics, and medical device coatings where long-term UV resistance and clarity are critical. Also serves as a ligand precursor in catalysis for palladium-mediated cross-coupling reactions due to its rigid bithiazole backbone. Shows promise in organic semiconductors for thin-film transistors owing to its electron-deficient character and thermal stability.
