Methyl Red is a maroon red crystal azo dye. Methyl red 0.02% solution in methanol is a dilute solution of the pH indicator methyl red dissolved in methanol. Methyl red, with the chemical formula C15H15N3O2, is an azo dye that changes color depending on the pH of the solution. In methanol, the indicator maintains its properties but is more suitable for certain applications where an aqueous solution might not be appropriate. Methyl red 0.02% solution in methanol is an effective pH indicator tailored for non-aqueous environments. It is also used for various applications in organic synthesis, chromatography, and industrial processes.

Application :

• Methyl red 0.02% in methanol is used in non-aqueous titrations, where methanol serves as a solvent instead of water. This is particularly useful in the titration of substances that are either insoluble or reactive in water.
• It is suitable for determining the pH of solutions in organic solvents, which is essential in various organic synthesis and pharmaceutical processes.
• It is used in thin-layer chromatography (TLC) and other chromatographic techniques where methanol-based solvents are employed. The indicator helps in visualizing pH changes during the separation process.

Benefits :

• Compatible with Organic Solvents
• Provides a clear and distinct color transition from red to yellow
• More effective and versatile
• Provides precise pH measurement and monitoring in non-aqueous media
