Phenolphthalein Powder – 25g LR Grade

This high‑purity Phenolphthalein Powder is supplied in a 25g container and manufactured to Laboratory Reagent (LR) Grade standards. With CAS No. 77‑09‑8, this indicator powder is ideal for preparing phenolphthalein solutions commonly used in school chemistry lessons.

Phenolphthalein is a widely used acid–base indicator, turning from colourless in acidic solutions to a vivid pink in alkaline conditions. This makes it an essential reagent for titration experiments, pH demonstrations, and a range of analytical chemistry activities in educational settings.

Supplied exclusively to educational establishments, this product ensures safe, reliable, and consistent performance in school laboratories.
