High Sensitivity in Metal Ion Detection

Pyrocatechol Violet is renowned for its exceptional sensitivity in detecting calcium and other metal ions. As a pH indicator, its color changes distinctly within the alkaline range (8.3 to 10.4), making it highly reliable for complexometric titrations and water hardness tests. This unique property ensures accurate and reproducible laboratory results.

Safe Handling and Storage Recommendations

Due to its toxic nature when ingested or inhaled, Pyrocatechol Violet requires cautious handling. Protective gear should be worn to prevent eye irritation and accidental intake. For durability, store the powder in its original sealed glass or HDPE container in cool, dry conditions, shielded from light. Proper storage maintains its efficacy throughout the 36-month shelf life.

Versatile Applications in Analytical Chemistry

This indicator is integral for both qualitative and quantitative analytical procedures. It serves as a reagent for identifying and quantifying metal ions, particularly in water samples. Its reliable performance and high purity allow chemists, process analysts, and water quality specialists to obtain accurate, defensible data.

FAQs of Pyrocatechol Violet:

Q: How is Pyrocatechol Violet typically used in laboratory analysis?

A: Pyrocatechol Violet is primarily used as an indicator in complexometric titrations and colorimetric analysis, especially for detecting calcium and other metal ions in water hardness and metal content analysis.

Q: What are the safety precautions when handling Pyrocatechol Violet powder?

A: Avoid ingesting or inhaling the powder, as it is poisonous and can cause eye irritation. Always use protective eyewear, gloves, and lab coats. Handle in a well-ventilated area and ensure containers remain sealed when not in use.

Q: Where should Pyrocatechol Violet be stored to maintain its stability?

A: Store it in a cool, dry location away from light and moisture, preferably in its original sealed glass bottle or HDPE container. Correct storage practices preserve its analytical properties for up to 36 months.

Q: What advantages does Pyrocatechol Violet offer as a pH indicator?

A: It provides clear color changes in the pH range of 8.3 to 10.4, allowing for precise detection during titrations involving calcium and other metal ions. This clarity supports more accurate and reliable laboratory measurements.

Q: When should Pyrocatechol Violet not be used in laboratory processes?

A: It should not be used beyond its shelf life, in applications that require a substance stable at high temperatures (since it decomposes before boiling or melting), or with acids/bases outside its effective pH indicator range.

Q: Is Pyrocatechol Violet soluble in common laboratory solvents?

A: Yes, it is soluble in both water and ethanol, facilitating its use in a variety of aqueous and organic analytical procedures.

Q: What benefit does high purity (>98%) provide for Pyrocatechol Violet in analytical applications?

A: High purity ensures consistent and accurate chemical behavior, reducing the risk of interference or errors during sensitive metal ion detection and titration processes.
