Production method It is derived from the condensation of phthalic anhydride and phenol.
Uses Phenolphthalein is one of those chemicals that is commonly used in the chemistry laboratory to tell if a solution is acidic or alkaline . These chemicals are called acid - base indicators and used as indicator for acidimetric titrations. Phenolphthalein exerts laxative effects by stimulating the intestinal mucosa and constricting smooth muscles. However, phenolphthalein is no longer used as a laxative due to the suspected carcinogenicity of this compound. Phenolphthalein can be used as an inhibitor and pH indicator. It also induces centrosome amplification and tubulin depolymerization in vitro.
