What is phenolphthalein used for?
Phenolphthalein is a colourless, weak acid that is widely used as an indicator in titration experiments to indicate the endpoint of the titration. The endpoint is indicated by the formation of a pink colour since this compound dissociates to form pink anions when dissolved in water.
What phenolphthalein is used for?
Is phenolphthalein a carcinogen?
It is more likely that the multiple biological properties of phenolphthalein, including its ability to form free radicals, its clastogenic activity, and its estrogenic activity, contributed to the carcinogenic effects observed. These studies show that phenolphthalein is a multisite/multispecies carcinogen.
