CAS 845-10-3
:Methyl red sodium salt
Description:
Methyl red sodium salt, with the CAS number 845-10-3, is a pH indicator commonly used in titrations and various laboratory applications. It is the sodium salt form of methyl red, which is a weak acid that exhibits a color change from red to yellow as the pH transitions from acidic to neutral. Specifically, methyl red has a pH transition range of approximately 4.4 to 6.2, making it particularly useful for detecting pH changes in acidic environments. The compound is typically soluble in water, and its solution appears red in acidic conditions and yellow in neutral to alkaline conditions. Methyl red sodium salt is often employed in microbiological media and as a biological stain due to its ability to indicate pH changes. Additionally, it is important to handle this substance with care, as it can be a mild irritant. Overall, methyl red sodium salt is a valuable tool in both analytical chemistry and biological research for monitoring pH levels.
