Uses of  Phenol Red

pH Indicator:

It is primarily used as a pH indicator in laboratory solutions. Its color change from yellow to red helps scientists and researchers determine the pH level of a solution visually.

Cell Culture:

In cell biology and microbiology, Phenol Red is often added to cell culture media to monitor pH changes. It helps maintain optimal pH conditions for cell growth and viability.

Environmental Monitoring:

It is used in environmental sciences to assess pH levels in water bodies and aquatic environments. Changes in its color indicate variations in pH, which can be critical for understanding environmental health.

Medical Diagnostics:

Phenol Red is also employed in medical diagnostics, particularly in urine tests. It can indicate changes in urinary pH, which may be indicative of certain health conditions or metabolic processes.

Chemical Analysis:

In chemical laboratories, Phenol Red can be used in titrations and other analytical techniques where pH monitoring is necessary for accurate results.
