– Chlorophenol red (Dichlorophenolsulphonephthalein) serves as a multifunctional dye with extensive applications in both scientific and industrial sectors. Within biological experiments, it facilitates the observation and analysis of cell structures, aids in tracking biomolecules, evaluating cell functions, distinguishing cell types, detecting biomolecules, studying tissue pathology, and monitoring microorganisms. Its uses extend beyond basic research to include clinical diagnostics. Furthermore, Chlorophenol red is employed in traditional industries like textile dyeing and emerging sectors such as functional textile processing, food pigments, and dye-sensitized solar cells.
