Used as a fluorescent labeling reagent in bioimaging and molecular probes due to its strong photostability and bright emission. Its bromomethyl functional group allows for easy conjugation to biomolecules such as proteins, nucleic acids, and small molecule tracers. Commonly employed in fluorescence microscopy, flow cytometry, and cellular tracking applications. The difluoro and methyl substitutions enhance fluorescence quantum yield and improve lipophilicity for better cell membrane permeability. Ideal for developing sensors and dyes in life science research and diagnostic assays.
