Phenol red exists as a red crystal that is stable in air. Its chemical formula is C19H14O5S. Phenol red is also known as phenolsulfonphthalein or PSP. Phenol red is a synthetic dye used as a pH indicator, changing color based on the pH of the solution. It gives yellow color below pH 6.8 and between 6.8 – 8.2 pH, it turns orange to red color. It turns pink to fuchsia color above pH 8.2. At a 1% concentration, phenol red appears as a deep red liquid in neutral to slightly basic solutions. This solution is typically prepared in water and can be used in various scientific and industrial applications to monitor pH levels. Phenol red 1% solution is a relatively high concentration of the pH indicator phenol red. This concentration is useful for applications requiring robust and highly visible pH changes.

Application :

• In higher concentration, phenol red 1% solution is used in assays where a strong and immediate visual pH indication is necessary, such as enzyme activity studies and other biochemical reactions.
• It is used in culture media to differentiate microbial species based on their metabolic activities that result in pH changes.
• While less common at this high concentration due to potential interference with some cellular processes, phenol red 1% can be used in cell culture media to provide a very sensitive pH indication.

Benefits :

• Provides a very distinct and easily noticeable color change
• Safe for use and versatile product
• Affordable
