Product Overview
Ammonium dihydrogen phosphate (NH₄H₂PO₄) of 99.999% purity (trace metal basis) is a high-grade crystalline powder designed for applications requiring minimal metallic contamination. This ultra-pure compound ensures accuracy in analytical chemistry, where trace impurities can significantly impact results. Its consistent composition makes it ideal for preparing buffer solutions, flame retardants, and other specialized formulations. The product undergoes rigorous quality control to maintain its high purity, ensuring reproducibility in sensitive experiments. Its low moisture content and stable shelf life further enhance its reliability for long-term storage and repeated use in laboratory settings. The trace metal basis specification guarantees that residual metals are kept below detectable thresholds, making it suitable for high-precision research and industrial applications where purity is non-negotiable.
FAQs
1. What is the difference between 99.999% and lower purity grades of ammonium dihydrogen phosphate?
The 99.999% grade ensures trace metal impurities are minimized to parts per million (ppm) levels, unlike lower grades where contaminants like iron, copper, or lead may interfere with sensitive analyses. This makes it ideal for applications requiring high precision.
2. Can this product be used in food or pharmaceutical applications?
While it is highly pure, this grade is specifically intended for laboratory and industrial use. For food or pharmaceutical applications, a grade compliant with respective regulatory standards (e.g., USP, FCC) would be required.
3. How should this product be stored to maintain its purity?
Store in a tightly sealed container in a cool, dry place, away from moisture and incompatible substances like strong oxidizers. Avoid prolonged exposure to air to prevent hydration or contamination.
4. Is this compound compatible with common laboratory solvents?
It is soluble in water and slightly soluble in ethanol but insoluble in most organic solvents. Always verify compatibility with your specific solvent system before use.
5. What alternatives exist if this purity grade is unavailable?
Lower purity grades (e.g., 99% or 99.5%) may suffice for less demanding applications, but they may introduce trace metal interferences. For critical work, consider purifying lower grades via recrystallization or sourcing from specialized suppliers.
