Methyl Red (ACS Reagent Crystalline)

Methyl Red is a pH indicator dye that shifts color according to acidity levels. It appears red in acidic solutions (pH below 4.4) and yellow in basic solutions (pH above 6.2), featuring an orange transition in between. This dye is widely used in microbiology and chemical titrations to monitor pH changes.
