Phenolphthalein, a cornerstone chemical in many laboratories, is celebrated for its distinct color-changing properties as a pH indicator. Its molecular formula, C20H14O4, belies its fundamental importance in accurately determining the endpoint of acid-base titrations. For any research scientist or product formulator, understanding and sourcing high-quality Phenolphthalein is crucial.

The magic of Phenolphthalein lies in its response to pH levels. In acidic and neutral conditions, it remains colorless. However, as the solution becomes alkaline, typically above a pH of 8.3, it transforms into a vibrant pink or fuchsia hue, a visual cue that signals the completion of a titration. This transition is incredibly valuable for chemists performing quantitative analyses. When you need to buy Phenolphthalein for your lab, ensuring purity is key for reliable results. Many suppliers offer it in various concentrations, often dissolved in alcohol for ease of use.

Beyond its primary role in titration, Phenolphthalein has found its way into other interesting applications. It’s used in the construction industry to test the carbonation of concrete, a process that affects its durability. In educational settings, it’s a staple for demonstrating fundamental chemical principles. Historically, it was also known for its use as a laxative, though this application has largely been discontinued due to health concerns.

For businesses seeking a reliable source for this essential chemical, identifying a reputable manufacturer or supplier is paramount. Companies looking to purchase Phenolphthalein in bulk can benefit from establishing relationships with established chemical distributors, particularly those specializing in fine chemicals or laboratory reagents. When considering your options, obtaining a price quote from a supplier in China can often be a cost-effective strategy, provided quality assurance is rigorously maintained.
