Methylthymol Blue, tetrasodium salt

Description:

Methylthymol Blue, tetrasodium salt, is a synthetic dye and pH indicator commonly used in various chemical and biological applications. It exhibits a distinct color change in response to pH variations, transitioning from yellow in acidic conditions to blue in alkaline environments. This property makes it valuable for titrations and as a visual pH indicator in laboratory settings. The compound is soluble in water, which enhances its utility in aqueous solutions. Its molecular structure includes a sulfonic acid group, contributing to its solubility and ionic nature. Methylthymol Blue is often employed in microbiological studies, as well as in the analysis of environmental samples. Safety data indicates that while it is generally considered low in toxicity, appropriate handling and safety measures should be observed, as with any chemical substance. Overall, Methylthymol Blue, tetrasodium salt, serves as an important tool in analytical chemistry and educational demonstrations, providing a clear visual representation of pH changes.
