As NINGBO INNO PHARMCHEM CO.,LTD., we recognize the foundational role that key chemical compounds play in scientific advancement. Among these, Phenolphthalein (CAS: 77-09-8) stands out for its long-standing utility as an acid-base indicator. Its ability to provide a clear visual signal at specific pH levels has made it an indispensable tool in chemical laboratories worldwide.

The primary application of Phenolphthalein revolves around its distinct color change. In acidic solutions (pH below 8.2), it remains colorless. However, as the solution becomes alkaline (pH above 8.2), it turns a vibrant pink or red. This predictable transition allows chemists to accurately determine the endpoint of neutralization reactions during titrations. Understanding these phenolphthalein chemical properties is crucial for any student or professional involved in quantitative chemical analysis.

Beyond its classic role in titrations, the versatility of Phenolphthalein is increasingly recognized. Its applications extend into areas such as diagnostic tests for certain biological activities and even into more specialized fields like the detection of lipase activity in crop seeds. The reliable phenolphthalein pH range of 8.2-10.0 ensures consistent results across these diverse uses. For those looking to buy phenolphthalein online, ensuring purity and accurate CAS number identification (77-09-8) is paramount for experimental success.

The phenolphthalein indicator applications are broad, encompassing not just academic research but also industrial quality control. Its stability and clear visual cues make it a preferred choice for many processes. While it's generally stable, awareness of its incompatibility with strong oxidizing agents and alkalies is essential for safe handling and storage.
