A Brief Introduction to Phenolphthalein Molecular Formula:C20H14O4 Molecular Weight:318.323 CAS No.:77-09-8 Appearance:White to slightly yellow crystalline powder Regular commercial package: 25kg/drum What is Phenolphthalein? Phenolphthalein is an organic compound that is relatively stable under normal temperature and pressure conditions. It is sparingly soluble in water and usually appears as a white or slightly yellowish crystalline powder. It is unstable under strongly acidic or strongly alkaline conditions and is readily soluble in ethanol. When Phenolphthalein encounters acidic or neutral solutions, no color change occurs, and the solution remains colorless; however, when Phenolphthalin encounters alkaline solutions, the solution turns purplish-red. This is why Phenolphthalein can be used as an indicator. It is typically used in solutions prepared with alcohol, for testing pH levels. It is not only convenient to use but also highly safe. Highassay’s Phenolphthalein Highassay offers two grades of Phenolphthalein powder raw material: high-purity Phenolphthalein powder and lower-purity Phenolphthalein powder.
One is a high-purity white crystalline powder. High-purity Phenolphthalein is typically used in laboratories for analytical purposes or as an indicator because it possesses extremely stable chemical properties, and its color change range as an indicator is the most accurate. Another type is Phenolphthalein with lower purity (containing impurities, such as substances similar to fluorescein) or that has undergone partial degradation (due to oxidation from air and light exposure over time). It typically appears as a pale yellow, light yellow, or off-white powder or crystals. Although the accuracy might be slightly compromised, it is generally acceptable for most experiments. As a controlled chemical substance, we provide an MSDS (Material Safety Data Sheet) with the product; please use it according to regulations. If you need to purchase Phenolphthalein raw materials, please choose Highassay; we will provide you with comprehensive service throughout the process. 更多
