Heptane for HPLC is a high‑purity, analytical‑grade organic solvent designed for use in pharmaceutical and analytical laboratories for HPLC mobile phase preparation, normal-phase chromatography, and improving separation efficiency.
🏭⚗️ Production
Distilled from ultra-pure heptane under strictly controlled conditions to remove impurities, including trace metals and water. Standardized for solvent purity, low UV absorbance, and stability. Supplied in chemically resistant, tightly sealed containers to prevent contamination, moisture uptake, or degradation.
🔬 Properties
A clear, colorless, volatile liquid with low viscosity and low UV absorption suitable for HPLC applications. Non-polar, highly flammable, and chemically stable under normal laboratory conditions. May form explosive mixtures with air; avoid sources of ignition. Store in a cool, dry, well-ventilated area away from heat, sparks, and oxidizing agents.
🧪 Applications
Used in pharmaceutical and analytical laboratories for preparing HPLC mobile phases, particularly in normal-phase separations, and for improving resolution of non-polar compounds. Often combined with polar modifiers to adjust selectivity and retention. Solutions and equipment must be handled carefully to maintain high analytical-grade purity and prevent contamination.
⚠️ Safety
Highly flammable and can cause skin and eye irritation, respiratory effects, or central nervous system depression if inhaled. Use in a well-ventilated area with appropriate protective equipment including gloves, goggles, and lab coat. Keep away from heat, sparks, open flames, and incompatible substances. Spills should be contained and cleaned according to institutional and environmental safety guidelines. Store in tightly closed, chemically resistant containers in a cool, dry, well-ventilated area.
