Product Overview
CHLOROPHENOL RED INDICATOR AR is a high-purity, analytical-grade pH indicator used to detect subtle pH changes in aqueous solutions. This synthetic dye transitions from yellow to red within the pH range of 4.8 to 6.4, making it a reliable choice for titrations, biological assays, and chemical analyses requiring precise endpoint detection. The reagent is soluble in water and ethanol, ensuring easy preparation of indicator solutions. Its AR-grade purity guarantees minimal interference from impurities, delivering consistent and reproducible results in laboratory settings. The powder form allows for flexible dosing, while the stable shelf life ensures long-term usability when stored under recommended conditions. Whether used in research, quality control, or educational experiments, this indicator provides clear visual confirmation of pH shifts, enhancing the accuracy of experimental procedures.
FAQs
1. What is the pH range for chlorophenol red indicator?
It transitions from yellow to red between pH 4.8 and 6.4, with a distinct color change at the midpoint.
2. Can this indicator be used in non-aqueous solvents?
It is primarily soluble in water and ethanol. For other solvents, test compatibility before use.
3. How should I store chlorophenol red to maintain stability?
Store in a cool, dry place in a tightly sealed container, away from direct light and moisture.
4. Is this indicator suitable for microbial growth media?
Yes, it can be used in microbiological assays where pH monitoring is required, provided sterility is maintained.
5. What alternatives exist for pH 4.8–6.4 range indicators?
Alternatives include bromocresol green (pH 3.8–5.4) or methyl red (pH 4.4–6.2), but transition ranges may vary.
