Product Overview
Ethyl Red is a synthetic azo dye widely used as a pH indicator in laboratory settings, offering a distinct color transition from red to yellow within the pH range of 4.4 to 6.2. This analytical-grade powder ensures high sensitivity and reliability in titration experiments, biochemical assays, and other applications requiring precise pH monitoring. Its fine particle consistency guarantees rapid dissolution in aqueous solutions, minimizing preparation time while maintaining accuracy. The dye’s stability under standard lab conditions makes it a preferred choice for researchers and educators conducting experiments where pH fluctuations must be visually tracked. Ethyl Red’s compatibility with common solvents and buffers further enhances its versatility, allowing seamless integration into diverse experimental protocols. Whether used in educational demonstrations or advanced research, this indicator delivers consistent performance, ensuring reproducible results. The 10 g pack size provides an optimal balance between cost-efficiency and supply longevity, reducing the need for frequent reorders while maintaining freshness.
FAQs
1. What is the pH range where Ethyl Red shows a color change?
Ethyl Red transitions from red to yellow between pH 4.4 and 6.2, making it suitable for monitoring acidic to slightly acidic conditions.
2. Can Ethyl Red be used in non-aqueous solvents?
While primarily designed for aqueous solutions, Ethyl Red can dissolve in certain polar organic solvents like ethanol, though color intensity may vary.
3. How should Ethyl Red be stored to maintain its shelf life?
Store in a cool, dry place away from direct sunlight and moisture, preferably in an airtight container to prevent degradation.
4. Is Ethyl Red compatible with other common pH indicators?
Yes, it can be used alongside indicators like Methyl Orange or Bromothymol Blue for broader pH range coverage in mixed indicator systems.
5. What alternatives exist if Ethyl Red is unavailable?
Methyl Red or Neutral Red can serve as substitutes, though their pH transition ranges differ slightly (Methyl Red: 4.4–6.0; Neutral Red: 6.8–8.0).
