phenol red

Phenol Red (Sulfonphthal) is a pH indicator, red dye, and diagnostic aid for measurement of renal function. It is used also for researches of the gastrointestinal and other systems.

Phenol Red sodium salt is a water-soluble pH indicator used in the range from 6.8 (yellow) to 8.2 (red).

Chlorophenol Red sodium serves as a pH indicator [1].

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.
