Acid-base titrations are fundamental analytical techniques across chemistry, and selecting the appropriate indicator is crucial for achieving accurate results. Phenol Red, a widely recognized sulfonephthalein dye, stands out as a highly effective pH indicator for titrations within a specific pH range. As a leading chemical manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. offers high-purity Phenol Red, ensuring that your titration experiments yield precise endpoints.
Phenol Red's utility in titrations stems from its distinct color transition. It exhibits a change from yellow in acidic solutions (pH below 6.6) to a vibrant red or reddish-violet in neutral to slightly alkaline solutions (pH between 8.0 and 8.2). This color change occurs within a pH range that is particularly useful for titrating weak acids with strong bases, or vice versa, where the equivalence point falls within this intermediate pH spectrum. For laboratories performing quantitative analysis, having a reliable source to buy Phenol Red is essential for consistent experimental outcomes.
The molecular formula for Phenol Red is C19H14O5S, with a molecular weight of 354.38. Its chemical structure allows for the visual detection of pH shifts, making it a staple in analytical chemistry. When you search for 'Phenol Red price' or 'buy Phenol Red,' it’s important to consider the purity and source. A high assay, such as the u226599.0% purity we provide, guarantees that the indicator's color change will be sharp and reliable, minimizing errors in titration endpoint determination.
NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing high-quality chemical reagents to research institutions, universities, and industrial clients. We understand that the success of your analytical work depends on the quality of the raw materials. Therefore, we ensure that our Phenol Red is manufactured under stringent quality control measures. Whether you need small quantities for educational purposes or bulk orders for industrial applications, we are equipped to meet your demands as a dependable chemical supplier.
For those looking to purchase Phenol Red for titration purposes, understanding its optimal usage range is key. While it’s excellent for mid-range pH titrations, other indicators might be preferred for strong acid-strong base titrations where the pH change is more abrupt. However, for many common analytical tasks, Phenol Red offers a clear, easily observable endpoint. We encourage you to partner with NINGBO INNO PHARMCHEM CO.,LTD. for your chemical reagent needs. Contact us today to learn more about our Phenol Red products, availability, and competitive pricing. Secure your supply of this vital titration indicator from a trusted manufacturer and supplier.
