The world of chemistry is often visualized through color, and few compounds illustrate this better than pH indicators. Methyl Red (CAS: 493-52-7) is a prime example, celebrated for its distinct and reliable color change within a specific pH range. This characteristic transition, from yellow to red between pH 4.4 and 6.2, is the cornerstone of its utility in various scientific applications, most notably in acid-base titrations and microbiological tests. For laboratories seeking accurate analytical tools, understanding this pH 4.4-6.2 color change is fundamental to its effective application. If you're looking to buy Methyl Red, ensuring the purity of the indicator guarantees a sharp and predictable color shift.

The precise pH range at which Methyl Red changes color is crucial for its performance. In acid-base titrations, the endpoint of a reaction occurs when the moles of acid and base are stoichiometrically equivalent. For titrations involving weak bases and strong acids, this equivalence point typically falls within an acidic pH range, often around 4.4 to 6.2. Methyl Red's transition range aligns perfectly with this, allowing analysts to visually pinpoint the endpoint with high accuracy. A faint pink or red hue indicates the approach to the endpoint, while a persistent red color signifies that the equivalence point has been reached or surpassed. This makes it an indispensable component for those performing acid-base titration indicator tasks, ensuring the precision of their quantitative results.

In microbiological studies, the color change of Methyl Red serves a different, yet equally important, purpose. The Methyl Red test is used to detect the production of stable acidic end-products by bacteria during fermentation. When Methyl Red is added to a bacterial culture that has undergone mixed acid fermentation, the accumulated acids cause the indicator to turn red, confirming the presence of these acidic metabolites. This application highlights Methyl Red’s role beyond a simple pH marker; it acts as a biochemical probe. Reliable sourcing from a Methyl Red supplier is essential for consistent results in these sensitive tests.

The reliability of Methyl Red's color change is also influenced by its concentration and the clarity of the solution being tested. As a dedicated Methyl Red manufacturer, we ensure our product is produced to high standards, providing a clear and vibrant color transition. When considering Methyl Red price, remember that the cost reflects the quality and consistency of this critical indicator. Whether for precise chemical titrations or insightful microbiological analysis, understanding and leveraging the specific pH 4.4-6.2 color transition of Methyl Red is key to achieving accurate and meaningful scientific outcomes.
