Product Overview

n-Hexane (96%+) in Extra Dry grade is a high-purity aliphatic solvent designed for critical laboratory applications where moisture sensitivity is a concern. The AcroSeal® packaging ensures long-term stability by minimizing exposure to atmospheric moisture, preserving the solvent’s integrity during storage and use. This grade is particularly valued for its low water content (<0.005%), making it suitable for applications requiring anhydrous conditions, such as gas chromatography (GC) and liquid-liquid extraction. The solvent’s narrow boiling range (68–70°C) and high volatility enable efficient evaporation without leaving residual impurities, which is essential for sample preparation in analytical workflows. Its chemical inertness and compatibility with most organic compounds further enhance its versatility in organic synthesis and purification processes. The Extra Dry specification is achieved through rigorous distillation and molecular sieve treatment, ensuring consistent performance in moisture-sensitive reactions. Whether used as a mobile phase in chromatography or a cleaning agent for lab equipment, this n-Hexane variant delivers reproducibility and reliability, reducing the risk of artifact formation in sensitive analyses.

FAQs

1. What is the difference between Extra Dry and standard n-Hexane?

Extra Dry n-Hexane undergoes additional drying processes, such as molecular sieve treatment, to reduce water content below 0.005%, whereas standard grades may contain higher moisture levels that can interfere with moisture-sensitive reactions or analyses.

2. Can this n-Hexane be used with plastic labware?

n-Hexane is compatible with most high-density polyethylene (HDPE) and polypropylene (PP) containers but may dissolve or swell polystyrene (PS) and some soft plastics. Always verify compatibility with your specific labware material before use.

3. How should Extra Dry n-Hexane be stored to maintain its purity?

Store the sealed AcroSeal® bottle in a cool, dry place away from direct sunlight and ignition sources. Once opened, minimize exposure to air by resealing tightly and using a desiccant cap if available to prevent moisture absorption.

4. Is this solvent suitable for food or pharmaceutical residue analysis?

While n-Hexane is commonly used in residue analysis, ensure compliance with specific regulatory standards (e.g., USP, EP) for food or pharmaceutical applications, as this grade is optimized for general lab use rather than certified for those industries.

5. What alternatives exist if n-Hexane is unavailable?

For similar applications, cyclohexane or heptane can be considered, though their polarity and boiling points differ. Cyclohexane is less volatile, while heptane offers a higher boiling point, which may affect extraction efficiency or chromatography resolution.
