Di ammonium hydrogen phosphate for HPLC

Di‑ammonium Hydrogen Phosphate for HPLC is a high‑purity, analytical‑grade buffer salt designed for use in pharmaceutical and analytical laboratories for preparing HPLC mobile phases, controlling pH, and stabilizing chromatographic separations.

🏭⚗️ Production
Manufactured from ultra‑pure di‑ammonium hydrogen phosphate crystals dissolved in deionized water under strictly controlled conditions to minimize trace metal and organic contaminants. Standardized for buffer capacity, molarity, and stability. Supplied in chemically resistant, tightly sealed containers to prevent contamination, moisture uptake, or degradation.

🔬 Properties
A white, crystalline powder highly soluble in water, forming a clear, colorless aqueous solution. Exhibits excellent buffering capacity in the pH range 6–8, low UV absorption suitable for HPLC, and high chemical stability. Non‑flammable under normal laboratory conditions but may react with strong acids or oxidizing agents. Store in a cool, dry, well‑ventilated area in appropriate containers.

🧪 Applications
Used in pharmaceutical and analytical laboratories for preparing HPLC mobile phases, adjusting pH in aqueous and mixed solvent systems, and improving reproducibility of chromatographic separations. Supports ion-exchange and reversed-phase HPLC with minimal background interference. Solutions and equipment should be handled carefully to maintain analytical-grade purity.

⚠️ Safety
Generally considered low hazard but can cause mild irritation to eyes, skin, and respiratory system. Use in a well-ventilated area with appropriate protective equipment including gloves and goggles. Avoid ingestion and contact with strong oxidizers or acids. Spills should be cleaned up according to institutional and environmental safety guidelines. Store in a tightly closed, chemically resistant container in a cool, dry, well-ventilated area away from incompatible substances.
