About Phenolphthalein Supplier 77-09-8 Phenolphthalein Powder

Phenolphthalein appears as white or yellowish-white to pale orange fine crystalline powder. Odorless. Aqueous solution is acidic. Colorless to pH 8.5; pink to deep-red above pH 9. Colorless in presence of large amounts of alkali. Tasteless.Phenolphthalein is an organic compound used as a laboratory reagent and pH indicator. 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.

Excellent Indicator for Laboratory Analysis

Phenolphthalein is widely employed as an acid-base indicator in titration procedures due to its distinct color change between pH levels 8.2 to 10.0, enabling precise detection. Its reliability and clarity make it an invaluable chemical reagent for research, quality control, and academic applications.

Secure Packaging and Extended Shelf Life

The product is available in robust 25 kg fiber drums or as per your requirements, ensuring safe handling and transportation. Phenolphthalein remains stable with a shelf life of up to 2 years when stored in tightly sealed containers at cool, dry conditions away from sunlight.

A: Phenolphthalein powder must be stored in a tightly sealed container, kept in a cool and dry place, and away from direct sunlight to maintain its stability and extend its shelf life up to two years.

Q: What is the main usage of phenolphthalein in laboratories and industries?

A: Phenolphthalein's primary application is as an acid-base indicator in titrations, but it is also utilized as a chemical reagent in laboratory research, pharmaceuticals, and chemical analysis.

Q: When is phenolphthalein beneficial as an indicator during chemical processes?

A: Phenolphthalein is highly beneficial in processes where precise pH measurement is required, such as titrations from acidic to basic conditions, as it exhibits a clear color change from colorless to pink above pH 8.2.

Q: Where is phenolphthalein typically produced and supplied from?

A: Phenolphthalein is distributed, exported, manufactured, and supplied primarily by producers in China, who offer it to laboratories, pharmaceutical companies, and chemical industries worldwide.

Q: What steps should be followed for safe handling and use of phenolphthalein powder?

A: Users should wear appropriate protective equipment and avoid ingestion since phenolphthalein is toxic in large amounts. It should not be mixed with strong oxidizing agents and must always be handled in well-ventilated areas.

Q: What packaging options are available for bulk orders of phenolphthalein?
