n‑Pentane for HPLC is a high‑purity, analytical‑grade 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 high 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, highly volatile liquid with a characteristic petroleum-like odor. Extremely flammable, low density, and low viscosity. Chemically stable under controlled conditions but reacts violently 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 other analytical procedures requiring high-purity non-polar solvents. Ensures reproducibility in chromatographic and extraction processes. Solutions and equipment should be handled to maintain analytical-grade purity.
⚠️ Safety
Highly flammable; can cause fire or explosion if exposed to heat, sparks, or open flames. May cause irritation to eyes and respiratory tract; prolonged inhalation can affect the central nervous system. 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 and ignition sources.
