Heptane is a high-purity, non-polar solvent widely used as a mobile phase, sample diluent, and extraction solvent in gas chromatography (GC) and analytical applications.

🏭⚗️ Production
Heptane is obtained through fractional distillation of petroleum fractions and further purified to remove impurities and moisture. The solvent is packaged in tightly sealed, moisture-resistant containers to ensure chemical stability and consistent performance in sensitive analytical procedures.

🔬 Properties
Heptane is a clear, colorless liquid with a low boiling point, low density, and high volatility. It is non-polar, immiscible with water, and an excellent solvent for non-polar compounds. Chemically stable under standard laboratory conditions, heptane is highly flammable and should be handled with caution. Its volatility and low polarity make it suitable for GC sample preparation, injection, and separation processes.

🧪 Applications
Heptane is used as a diluent and extraction solvent for non-polar analytes in GC analysis. It serves as a mobile phase in chromatographic separations and is employed in sample preparation and standard solution preparation. Its low polarity allows for accurate and reproducible results when analyzing non-polar compounds.

⚠️ Safety
Heptane is highly flammable and can be harmful if inhaled or absorbed through the skin. Handling requires gloves, protective eyewear, and lab coats, and work should be conducted in a well-ventilated fume hood. Containers must be stored sealed, away from heat, sparks, and strong oxidizers. Waste must be disposed of according to laboratory hazardous chemical regulations.
