Phenol red chemical formula is C19H14O5S. It is also known as phenolsulfonphthalein or PSP. Phenol red is commonly used as a pH indicator, as it changes color depending on the pH of the solution. It appears yellow below pH 6.8, orange to red between pH 6.8 and 8.2, and pink to fuchsia above pH 8.2. When present in a 1% concentration, phenol red takes the form of a deep red liquid in neutral to slightly basic solutions. This solution is typically prepared in water and is utilized in various scientific and industrial applications to monitor pH levels. The 1% concentration of phenol red is particularly beneficial for applications that require strong and easily noticeable 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
