pH 6.8 (yellow) - pH 8.2 (red) Ready-to-use reagent. Prepared with ACS reagent grade Phenol Red and high purity water. Suitable for laboratory use.

Product Overview

Phenol Red is a widely used sulfonephthalein dye that functions as a pH indicator across the range of 6.8 to 8.4, changing color from yellow (acidic) to red (neutral) to fuchsia (alkaline). It is especially valuable in biological and clinical laboratories due to its compatibility with physiological systems and its use in monitoring pH in cell culture media.

In addition to cell culture, Phenol Red is used in water quality testing, enzyme assays, and general acid-base titrations. Its clear color transitions and low toxicity make it ideal for sensitive applications.

Key Features:

  • pH transition range: 6.8 (yellow) to 8.4 (fuchsia)
  • Compatible with biological and clinical systems
  • Commonly used in cell culture as a visual pH monitor
  • Available in powder or solution form
  • Stable under typical storage conditions

Applications:

  • pH monitoring in cell and tissue culture media
  • Acid-base titrations in mid-range pH environments
  • Buffer system validation and testing
  • Water quality and environmental analysis
  • Indicator in enzymatic or biochemical assays

Phenol Red offers reliable, non-intrusive pH monitoring in a broad range of research, industrial, and diagnostic applications, especially where biological compatibility is essential.
