In any scientific or industrial application that relies on precise chemical reactions, the quality of the reagents used is paramount. Phenol Red, with its CAS number 143-74-8, is a widely utilized compound, most commonly known for its function as a pH indicator. However, when procuring Phenol Red, especially for critical applications such as pharmaceutical intermediates or sensitive biological assays, understanding the factors that contribute to its quality is essential. This guide aims to illuminate the key aspects of quality assurance when you decide to buy Phenol Red, highlighting why sourcing from reputable manufacturers like NINGBO INNO PHARMCHEM CO.,LTD., a leading supplier in China, is crucial.

The intrinsic properties of Phenol Red, such as its molecular formula (C19H14O5S) and its characteristic yellow-to-red color change within the pH range of 6.6 to 8.0, are fundamental. However, for consistent and reliable performance, several quality parameters must be met. Purity is a primary concern; impurities can interfere with the indicator’s accuracy or lead to unwanted side reactions in synthesis. For example, in pharmaceutical intermediate applications, even trace impurities can have significant downstream effects. Therefore, verifying the purity level, often indicated by analytical data like HPLC or GC reports provided by the supplier, is a critical step in the quality assurance process. When you buy Phenol Red, always look for detailed specifications.

Beyond chemical purity, consistency between batches is another vital aspect of quality assurance. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. implement stringent quality control measures to ensure that each batch of Phenol Red meets the same high standards. This consistency is crucial for reproducible results, whether in routine laboratory testing, large-scale industrial processes, or research that requires long-term monitoring. Factors such as particle size, solubility, and stability under recommended storage conditions (e.g., storing at room temperature) also contribute to the overall usability and reliability of the product. Ensuring these parameters are consistently met is a hallmark of a dependable supplier in China.
