Nitric Acid 69% Ultrapure is a high‑purity, analytical‑grade reagent used in pharmaceutical and analytical laboratories for HPLC mobile phase preparation, digestion, oxidation reactions, and pH adjustment.
🏭⚗️ Production
Prepared from ultra‑pure nitric acid synthesized and distilled under strictly controlled conditions to minimize trace metals and contaminants. Standardized for concentration, density, and solution stability. Supplied in chemically resistant, tightly sealed containers to prevent contamination, moisture uptake, or degradation.
🔬 Properties
A colorless to slightly yellow liquid with a sharp, acrid odor. Strongly acidic, highly oxidizing, and highly soluble in water. Exhibits chemical stability under controlled laboratory conditions but reacts vigorously with organic materials, bases, and reducing agents. Corrosive to metals and tissues. Store in a cool, dry, well‑ventilated area in containers resistant to acids and oxidation.
🧪 Applications
Used in pharmaceutical and analytical laboratories for HPLC mobile phase preparation, controlled oxidation reactions, sample digestion, and pH adjustment in aqueous and mixed solvent systems. Supports reproducible chromatographic separations while minimizing background interference. Solutions and equipment should be handled carefully to maintain analytical-grade purity.
⚠️ Safety
Corrosive and highly oxidizing; can cause severe burns to eyes, skin, and respiratory tract. Inhalation of fumes may cause respiratory irritation. Highly reactive with organics and reducing agents. Use in a well‑ventilated area with appropriate protective equipment including gloves, goggles, and lab coat. Avoid ingestion and contact with incompatible substances. Spills should be neutralized and 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 materials.
