Product Overview

Methyl Red is a classic azo dye pH indicator used extensively in acid-base titrations and buffer system evaluations. It exhibits a clear and sharp color transition from red to yellow over the pH range of 4.2 to 6.2, making it especially useful in the analysis of weak acid–strong base systems and in monitoring pH changes near mildly acidic conditions.

Its ease of use and reproducible color shift make Methyl Red a staple in laboratory analysis, educational instruction, and water chemistry. It is available in both powder and ready-to-use solution formats.

Key Features:

• pH transition range: 4.2 (pink) to 6.2 (yellow)
• Clear visual endpoint in mid-acidic pH region
• Useful for titrations and buffer characterization
• Available in dry and solution forms
• Long shelf life and good stability under standard conditions

Applications:

• Weak acid–strong base titrations
• Buffer solution evaluation and formulation
• Environmental and water chemistry testing
• pH visualization in chemical and biological studies
• Educational demonstrations in general chemistry

Methyl Red delivers consistent, easy-to-read results and remains a trusted indicator for both analytical and instructional environments requiring precision in mid-range pH detection.
