Phenolphthalein, a compound readily identified by its CAS number 77-09-8, is a versatile substance with significant applications ranging from precise laboratory measurements to the formulation of everyday consumer products. Its most widely recognized utility is as a pH indicator. In environments with a pH below 8.2, Phenolphthalein remains colorless. However, as the pH rises into the alkaline spectrum (8.2-10.0), it undergoes a visible transformation to a distinct pink hue. This property makes it an invaluable tool for chemists performing titrations, enabling accurate identification of reaction endpoints and ensuring reliable analytical results. The availability of high-purity Phenolphthalein powder, often at 99% assay, is crucial for maintaining the integrity of these scientific endeavors.

Beyond its analytical roles, Phenolphthalein also serves as an important ingredient within the realm of cosmetic raw materials and oral care chemicals. The quality and safety standards for these product categories are exceptionally high, making the sourcing of pure and stable Phenolphthalein a priority for manufacturers. Reliable Phenolphthalein suppliers are essential for businesses that depend on a consistent and quality-assured supply chain. The stability of the compound, provided it is stored correctly, also contributes to its value as a long-lasting ingredient.

When businesses decide to buy Phenolphthalein, they typically consider several factors. These include the product's physical form (commonly a white powder), its CAS number (77-09-8), and the purity level required for their specific application. Researching options for Phenolphthalein for sale allows for price and quality comparisons. Proper storage is a key recommendation: keeping the compound sealed in a cool, dry place away from direct light and moisture helps maintain its shelf life, which is typically up to two years when stored properly.

The importance of Phenolphthalein in fields such as pH indication and its contribution to innovation in product development highlight its ongoing relevance. Whether used in academic research or commercial manufacturing, Phenolphthalein with CAS 77-09-8 remains a key chemical. Companies that prioritize quality when they purchase Phenolphthalein ensure that their own operational standards and product outputs are maintained at the highest level.
