Phenolphthalein is an organic compound that is used as a laboratory reagent as well as a pH indicator. It appears as a yellowish-white fine crystalline powder and is a member of phenols.  Additionally, it exerts laxative effects as it stimulates the intestinal mucosa but is no longer used as a purgative tool due to the carcinogenicity of this compound. 

Phenolphthalein, 1 Percent (w/v) Indicator Solution in 95 Percent Ethyl Alcohol is often used as a indicator in titrations and is colorless in acidic solutions and pink in basic solutions. LabChem solutions utilize the highest quality raw materials. Most raw materials meet or exceed the specifications established by the American Chemical Society. Where appropriate, many finished products are traceable to NIST Standard Reference Materials. Manufacturing, quality control testing, and packaging are all performed in LabChem's own facilities. Record keeping and sample retention of all produced lots ensure product consistency and complete traceability.
