For procurement managers in the chemical, pharmaceutical, and research sectors, sourcing high-quality Phenolphthalein (CAS 77-09-8) is a critical task that ensures the accuracy and reliability of their processes. As a leading manufacturer and supplier of Phenolphthalein in China, NINGBO INNO PHARMCHEM CO.,LTD. understands the essential specifications and applications that matter to our B2B clients.

When looking to buy Phenolphthalein, key considerations include purity, consistency, and application suitability. Our Phenolphthalein is typically offered with an assay of 98%-101%, ensuring it meets stringent analytical standards. Its appearance as a white crystalline powder is consistent across batches, a testament to our quality control processes.

The primary application for Phenolphthalein is as an acid-base indicator in titrations. Its distinct color change from colorless to pink within the pH range of 8.2-10.0 makes it ideal for determining the endpoint of reactions involving bases. Beyond the lab, it finds critical use in forensic science for the Kastle-Meyer presumptive blood test and in the construction industry for assessing concrete carbonation. While its historical use as a laxative has declined due to safety regulations, its industrial and analytical applications remain robust.
