Benzene 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 sweet aromatic odor. Flammable, low density, and low viscosity. Chemically stable under controlled conditions but can form explosive peroxides and reacts with strong oxidizers. 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. Helps maintain reproducibility and purity in chromatographic and extraction processes. Solutions and equipment should be handled carefully to preserve analytical-grade quality.
⚠️ Safety
Highly flammable and toxic; prolonged exposure can affect the central nervous system and cause dizziness, headaches, or long-term health effects. May irritate 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.
