Product Overview
Bromocresol Green Indicator (95% AR/ACS) is a synthetic dye widely used in analytical chemistry for its sharp color transition in acidic to neutral pH ranges. This high-purity indicator, compliant with AR (Analytical Reagent) and ACS (American Chemical Society) standards, ensures consistent and reliable results in titrations and pH measurements. The dye exhibits a distinct color change from yellow (pH 5.4), making it ideal for detecting endpoint reactions in laboratory procedures. Its alcohol-soluble nature allows for easy preparation of indicator solutions, while its stability under standard lab conditions ensures long-term usability. The AR/ACS grade guarantees minimal impurities, reducing interference in sensitive experiments. Whether used in qualitative analysis or quantitative assays, this Bromocresol Green Indicator delivers precision and reproducibility, meeting the stringent requirements of research and educational laboratories. Store in a cool, dry place away from direct sunlight to maintain its efficacy.
FAQs
1. What is the pH range for Bromocresol Green Indicator?
Bromocresol Green transitions from yellow to blue between pH 3.8 and 5.4, making it suitable for detecting acidic to slightly acidic conditions.
2. Can this indicator be used in aqueous solutions?
It is primarily soluble in alcohol. For aqueous use, dissolve it in ethanol first, then dilute with water to the required concentration.
3. Is this product compatible with non-aqueous titrations?
Yes, Bromocresol Green can be used in non-aqueous solvents like ethanol or methanol, provided the solvent does not interfere with its color change.
4. How should I store this indicator to maintain its shelf life?
Store in an airtight container in a cool, dry place, protected from light and moisture to prevent degradation.
5. Are there alternatives to Bromocresol Green for similar pH ranges?
Alternatives include Methyl Red (pH 4.4–6.2) or Bromophenol Blue (pH 3.0–4.6), though their transition ranges differ slightly.
