Product Overview
Methyl Thymol Blue AR is a synthetic pH indicator widely used in analytical chemistry for its sharp color transitions in acidic and alkaline solutions. This AR-grade reagent offers exceptional purity, ensuring accurate endpoint detection in titrations. The powder form dissolves readily in water and ethanol, making it versatile for various laboratory protocols. Its distinct color change from red to yellow across pH 1.2?2.8 and blue to yellow across pH 8.0?9.6 allows precise pH determination. The reagent is stable under standard lab conditions but should be stored in a cool, dry place to maintain efficacy. Ideal for applications requiring high sensitivity, Methyl Thymol Blue AR delivers consistent performance in qualitative and quantitative analysis.
