Sodium Acetate for HPLC is a high‑purity, analytical‑grade salt used in pharmaceutical and analytical laboratories for HPLC mobile phase preparation, buffer systems, and pH control.
🏭⚗️ Production
Prepared from ultra‑pure sodium acetate under strictly controlled conditions to minimize trace metals, moisture, and other impurities. Standardized for concentration, chemical stability, and buffer capacity. Supplied in chemically resistant, tightly sealed containers to prevent contamination, moisture uptake, or degradation.
🔬 Properties
A white crystalline powder, odorless, highly soluble in water, and slightly hygroscopic. Chemically stable under normal laboratory conditions. Forms buffer solutions with acetic acid. Store in a cool, dry, well‑ventilated area, protected from strong acids and oxidizers.
🧪 Applications
Used in pharmaceutical and analytical laboratories to prepare HPLC mobile phases, buffer solutions, and pH-adjusted systems. Helps maintain reproducibility and stability in chromatographic separations. Solutions and equipment should be handled carefully to preserve analytical-grade purity.
⚠️ Safety
Generally considered low-toxicity, but may cause mild irritation to eyes, skin, and respiratory tract. Avoid ingestion and prolonged exposure. Use in a well‑ventilated area with appropriate protective equipment including gloves, goggles, and lab coat. Store in a tightly closed, chemically resistant container in a cool, dry, well‑ventilated area away from incompatible substances.
