Phenolphthalein (CAS: 77-09-8) is a classic example of a compound whose familiar function as a pH indicator belies a more detailed profile of phenolphthalein chemical properties and handling considerations.

Understanding the physical and chemical characteristics of Phenolphthalein is paramount for its effective use. It presents as a white to yellow-white solid, with a melting point between 261-263°C. Its solubility in alcohol is a key feature, while it shows limited solubility in ether and is practically insoluble in benzene and hexane. The compound's phenolphthalein stability is generally good under ambient conditions, though it's important to note its incompatibility with strong oxidizing agents and alkaline substances, which can degrade the compound or cause unintended reactions.

The most recognized attribute of Phenolphthalein is its performance as an indicator. The well-defined phenolphthalein pH range, from approximately 8.2 (colorless) to 10.0 (pink/red), makes it exceptionally useful for titrating weak acids with strong bases. However, its applications are not limited to this. The compound's ability to interact with various substances leads to its use in specialized testing kits and industrial processes.
