Toluene for HPLC is a high‑purity, analytical‑grade aromatic solvent used in pharmaceutical and analytical laboratories for HPLC, extraction, and sample preparation.
🏭⚗️ Production
Distilled and purified under strictly controlled conditions to minimize water, peroxides, and trace impurities. Standardized for chemical purity, low water content, and hydrocarbon stability. Supplied in chemically resistant, tightly sealed containers to prevent contamination, moisture uptake, or degradation.
🔬 Properties
A colorless, volatile liquid with a characteristic aromatic odor. Flammable, low density, and low viscosity. Chemically stable under controlled conditions but reacts with strong oxidizers and can form explosive peroxides over time. Store in a cool, dry, well-ventilated area, away from heat, sparks, open flames, and incompatible substances.
🧪 Applications
Used in pharmaceutical and analytical laboratories for HPLC mobile phase preparation, extraction of non-polar compounds, and analytical procedures requiring high-purity aromatic solvents. Maintains reproducibility and purity in chromatographic and extraction processes. Solutions and equipment should be handled carefully to preserve analytical-grade quality.
⚠️ Safety
Highly flammable; prolonged exposure can affect the central nervous system causing dizziness, headaches, or long-term health effects. May cause irritation to eyes, skin, and respiratory tract. Use in a well‑ventilated area with appropriate protective equipment including gloves, goggles, and lab coat. Avoid ingestion and contact with incompatible substances. Store in a tightly closed, chemically resistant container in a cool, dry, well‑ventilated area away from oxidizers, heat, and ignition sources.
