Applications
Phenol Red sodium salt commonly employed in cell biology laboratories as a cell tissue culture pH marker. Under normal conditions, phenol red added to the growth medium will have a pink-red color. If their is dying cells or overgrowth of contaminants, this will cause a change in pH resulting in a change in indicator color. This color change is an indication that the medium needs to be replaced. Additionally, Phenol Red could potentially be useful as a differentiation factor.

Solubility
Soluble in water yielding a dark red solution (25 mg/ml), alcohol (4 mg/ml), methanol, ethanol (200 mg/ml), and aqueous alkali hydroxides or carbonates with formation of a red colored solution.

Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
