Precise measurement is the cornerstone of effective chemical analysis, and M-Cresol Purple Sodium Salt (CAS 62625-31-4) stands out as a critical reagent for achieving this precision. At NINGBO INNO PHARMCHEM CO.,LTD., we are proud to supply this versatile sulfonephthalein dye, understanding its significant contributions to various analytical techniques, particularly titrations. The specific m-cresol purple sodium salt pH range is key to its analytical performance.

Titration is a common quantitative chemical analysis technique used to determine the concentration of a substance. It involves the gradual addition of a solution of known concentration (titrant) to a solution of unknown concentration (analyte) until the reaction between them is just complete. An indicator is crucial for signaling the completion of this reaction, known as the equivalence point. M-Cresol Purple Sodium Salt serves this purpose admirably, exhibiting clear color changes at specific pH values.

The dual pH transition ranges of M-Cresol Purple Sodium Salt are particularly advantageous. It transitions from red to yellow between pH 1.2 and 2.8, and then from yellow to purple between pH 7.4 and 9.0. This allows it to be used in titrations involving both moderately strong acids and bases, as well as in situations requiring the observation of pH changes in specific buffers or solutions. The ability to buy M-Cresol Purple Sodium Salt with confidence means researchers can rely on consistent results.

The appearance of M-Cresol Purple Sodium Salt as an orange-brown to black powder, coupled with its good solubility in water, makes it easy to handle and prepare for titration procedures. When choosing an indicator, chemists consider not only the pH range but also the clarity of the color change and the compound's stability. M-Cresol Purple Sodium Salt fulfills these requirements, making it a staple in many analytical laboratories.

For researchers and chemists who require accurate endpoint determination, M-Cresol Purple Sodium Salt is an indispensable tool. Its properties as a sulfonephthalein dye ensure that subtle pH shifts are visually detectable, thereby enhancing the reliability of analytical results. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing the high-quality chemical reagents that power scientific discovery. When you need to buy M-Cresol Purple Sodium Salt for your analytical needs, consider our commitment to purity and performance.
