Phenolphthalein Powder Extra Pure is a high-purity pH indicator extensively used in analytical chemistry and laboratory applications. This fine, white to pale pink crystalline powder is colorless in acidic solutions but turns a vivid pink to deep magenta in basic environments, typically transitioning around a pH of 8.2 to 10.0. Its sharp and distinct color change makes it ideal for acid-base titrations, particularly in educational, industrial, and research settings.

In addition to its primary role in titrations, Phenolphthalein is also used in various chemical formulations, soil pH testing, and sometimes as a dye component in forensic applications. Although previously used as a laxative, it is now restricted to laboratory use due to health concerns. It should be handled with care—using gloves, protective eyewear, and in well-ventilated areas—to avoid inhalation or prolonged contact. Store in a cool, dry place, away from strong oxidizers and light.
