Phenol red is used as non absorbed marker in the gravimetric method. It is a pH indicator used in cell biology laboratories and in home swimming pool test kits. It is used to check the kidney function based on the excreted phenol red by colorimetric method.

Phenol Red is a compound widely used in culture media which identifies pH changes from neutral (red) to acidic (yellow) values. Typically a change in color from red to yellow indicates high rates of cellular death when used in tissue cultures. In the culture of breast cancer cells Phenol Red has been observed to act as a weak estrogen. In human MCF-7 cells, phenol red has reduced Roscovitine (sc-24002) mediated cell cycle arrest and apoptosis. Phenol red has also induced oogenesis from cells scraped from the surface of adult ovaries.

Phenol red is a pH indicator that finds broad applications from chemistry to microbiology. Colour varies from yellow at pH<6.8 (lmax 443nm) through to light red/pink at 6.88.2. It is widely used in cell culture to monitor pH and for colorimetric titration. For example, phenol red can be used to quantify Br- content in sea or fresh water. It is added to VTM as pH indicator, at the concentration of 10mg/ml, maintaining a pink colour at neutral pH.
