The Methyl Red (CI 13020) ACS Analytical Grade by Dinâmica, available at LojaLab, is an azo indicator used in titrations, acidity analysis and microbiological tests. Its typical visual transition occurs from pH 4.4 to 6.2: red predominates below the range, orange appears through the transition and yellow predominates above it. The solid reagent allows indicator solutions to be prepared at the concentration and in the solvent defined by the procedure.
