Versatile Acid-Base Indicator for Laboratory Analysis

Bromopyrogallol Red is valued for its distinct and easily observable color transitions in the pH range 3.2 (yellowish) to 4.4 (red), making it an essential choice for titrimetric analysis. Its water and ethanol solubility, combined with compatibility with most laboratory reagents, supports flexible usage in analytical and research settings.

Safe Handling and Storage Recommendations

For optimal stability, BPR should be preserved in tightly sealed amber glass or HDPE containers away from light and moisture. Proper handlingusing gloves and eye protectionis critical, as the powder is an irritant and may be harmful if inhaled or swallowed. Dispose of in accordance with relevant regulations to ensure safety.

FAQs of Bromopyrogallol Red:

Q: How should Bromopyrogallol Red be stored to maintain its quality?

A: Bromopyrogallol Red should be stored in a cool, dry location inside tightly closed containers, such as amber glass bottles or HDPE packaging, and protected from direct light and moisture. This approach ensures product stability and preserves its indicative properties, securing a shelf life of at least three years.

Q: What are the primary applications and benefits of BPR in a laboratory setting?

A: Bromopyrogallol Red is mainly used as a complexometric indicator in analytical titrations and for biological staining. It offers clear, distinct color transitions over a narrow pH range, improving endpoint detection and analytical accuracy in research and quality control.

Q: When is it appropriate to use Bromopyrogallol Red during titration?

A: BPR should be used when performing complexometric titrations or any procedures needing an indicator sensitive to pH changes between 3.2 and 4.4. Its color change from yellowish to red distinctly marks the endpoint, enhancing analytical precision.

Q: What precautions must be taken when handling or disposing of BPR?

A: Protective gear such as gloves and safety goggles should be worn when handling Bromopyrogallol Red, as it is an irritant and may be hazardous if inhaled or ingested. Disposal must follow local, regional, or national chemical regulations to avoid environmental contamination.

Q: How compatible is Bromopyrogallol Red with other reagents?

A: BPR demonstrates stable compatibility with the majority of laboratory reagents, minimizing risks of adverse reactions or decomposition during typical analytical applications, thereby ensuring consistent results.

Q: Where is Bromopyrogallol Red manufactured and supplied from?

A: This high-purity, analytical reagent is manufactured, exported, and supplied by reputable chemical producers in India, readily available in common pack sizes suitable for laboratory and industrial requirements.
