While Phenol Red (CAS 143-74-8) is primarily recognized for its function as an acid-base indicator, its utility extends far beyond simple pH titrations. For research and development scientists, understanding the multifaceted applications of this chemical can unlock new possibilities in experimentation and analysis. As a leading provider of fine chemicals, our role as a manufacturer and supplier from China is to equip you with high-quality reagents that support your groundbreaking work.

The well-known discoloration range of Phenol Red, from pH 6.8 to 8.4, makes it an essential tool for chemists conducting titrations to determine the concentration of acids and bases. However, its application as a pH indicator is also vital in biochemical research where maintaining specific pH levels is critical for enzyme activity and cellular processes. Researchers often use Phenol Red in buffer solutions or cell culture media to visually monitor pH changes and ensure optimal experimental conditions.

In the field of microbiology, Phenol Red serves as a valuable component in diagnostic media. For instance, it is incorporated into carbohydrate fermentation broths. Different microorganisms metabolize specific sugars, producing acidic byproducts that lower the pH, causing the Phenol Red to change color. This color change acts as a clear indicator of the organism's metabolic capability, aiding in bacterial identification and differentiation. For scientists needing reliable results, sourcing Phenol Red from a reputable China manufacturer is key to consistent performance in these assays.

Furthermore, Phenol Red plays a role in clinical chemistry. Its sodium salt is employed in tests to assess liver function, specifically in evaluating the liver's ability to excrete dyes. This application highlights the diagnostic significance of Phenol Red in medical laboratories. The substance is also used in measuring the total carbon dioxide content in blood, contributing to the understanding of respiratory and metabolic states.
