In the meticulous world of chemical analysis and laboratory science, selecting the appropriate pH indicator is critical for obtaining accurate and reliable results. While a variety of indicators exist, each with its unique pH transition range and color change, Methyl Red (CAS: 493-52-7) stands out for its specific applications, particularly in acid-base titrations and microbiological testing. Understanding these applications helps researchers and technicians make informed decisions when sourcing their laboratory reagents. If your work requires precise pH monitoring within a specific range, learning how to buy Methyl Red is a valuable step.

Methyl Red is particularly favored as an acid-base titration indicator when dealing with the titration of weak bases with strong acids, or weak acids with strong bases where the equivalence point falls in the acidic region. Its color transition, from yellow at pH 6.2 to red at pH 4.4, precisely brackets the pH change expected at the equivalence point for many such reactions. This sharp, easily discernible color change minimizes titration errors. For example, in determining the concentration of ammonia or other weak organic bases, Methyl Red provides a more accurate endpoint signal than indicators that change color at neutral or alkaline pH values. Working with a reputable Methyl Red supplier ensures that the product's purity guarantees this precise transition, making your titration results more dependable.

In microbiology, Methyl Red finds its niche in the Methyl Red (MR) test, a key diagnostic tool for identifying bacteria. This test differentiates organisms based on their ability to produce stable, acidic end-products from glucose fermentation through the mixed acid pathway. When Methyl Red is added to a cultured broth, a red color indicates a positive result, signifying significant acid production. A yellow color suggests the absence of such acidic end-products, often pointing to the butanediol fermentation pathway. This is a fundamental method for bacterial classification and identification in clinical and research settings. The reliability of the MR test hinges on the quality of the Methyl Red used, highlighting the importance of selecting a high-quality product when considering Methyl Red price.

As a leading Methyl Red manufacturer in China, we understand the critical role this compound plays in scientific research and industry. The consistent quality and performance of Methyl Red are paramount, whether it’s used in titrations or diagnostic tests. Therefore, choosing a supplier that prioritizes purity and adherence to specifications is essential. By focusing on the specific applications where Methyl Red excels, scientists can ensure the accuracy and efficiency of their laboratory procedures, reinforcing its value as a staple chemical reagent.
