Xylenol Blue is a man-made sulfonephthalein dye that is usually in powder or crystalline form in a dark brown. Having a chemical formula of C23H22O5S, it is slightly soluble in water and soluble in organic solvents such as ethanol and methanol. Xylenol Blue exhibits a different color (yellow in acidic and blue in basic situations, yellow in the middle) with respect to pH: at pH 1.2, the color changes to yellow, at pH 9.6 to blue and in the middle of the pH range to yellow. With its stable and repeatable color changes, it is a valuable pH indicator across laboratory, educational and industrial use.

Applications

  • Used as a pH indicator in precise acid-base titrations.
  • Enhances biological, histological staining to visualize the cellular structures and parts.
  • Usually used in microbiology, such as analysis of bacterial growth, microbial assays, and assay of enzymes (lipase).

Key features

  • Reliable Accuracy: Offers precise pH readings and consistent analytical results.
  • Stable & Versatile: Performs reliably in a wide range of laboratory and industrial conditions.
  • Affordable & Efficient: Cost-effective solution suitable for research laboratories and educational institutions.

General Description

Xylenol Blue C23H22O5S is a little water-soluble and highly soluble in ethanol and methanol. It is used in analytical chemistry, microbiology, and biological staining because it has a reproducible colour change and is stable. Xylenol Blue is also ideal to use in laboratory work as well as in teaching demonstrations because researchers and educators find it sensitive and reliable.
