Phenol Red Indicator

Product Description:Phenol Red Indicator

Phenol Red (C₁₉H₁₄O₅S), alsPhenol Red Indicatoro known as Phenolsulfonphthalein (PSP), is a pH indicator dye commonly used in cell culture, microbiology, and laboratory experiments. It is a weak acid that exhibits distinct color changes depending on the pH of the solution: yellow in acidic medium, red at neutral pH, and pink/violet in alkaline conditions.

Phenol Red is supplied in powder form or as a ready-to-use aqueous/ethanol solution, making it ideal for analytical chemistry, educational labs, and biological research.
