What is n-Hexane?

n-Hexane (C₆H₁₄, CAS No. 110-54-3) is a straight-chain hydrocarbon widely used in HPLC and analytical applications for its purity, volatility, and hydrophobic nature. Often confused with glucose (C₆H₁₂O₆), it is distinctly non-polar and ideal for solvent systems. Refined for minimal UV absorbance and high inertness, n-Hexane for HPLC ensures precise, consistent results in pharmaceutical, environmental, food, and chemical labs, making it a trusted choice for high-resolution chromatographic analysis. 

Key Chemical Properties of n-Hexane

n-Hexane offers several distinct chemical properties that make it suitable for analytical-grade applications: 

  • Purity: Refined to contain minimal non-volatile matter and moisture content for optimal HPLC use 
  • Boiling Point: Approximately 68.7°C 
  • Solubility: Insoluble in water; soluble in ether, alcohol, and chloroform 
  • Volatility: Highly volatile, making it ideal for solvent extraction processes 
  • UV Transparency: Very low UV absorbance, essential for sensitive detection in chromatographic applications 
  • Chemical Stability: Resistant to degradation under normal laboratory conditions 

These characteristics support n-hexane’s widespread use in HPLC, where solvent consistency and purity are crucial for accurate sample analysis. 

In certain reversed-phase methods, Acetonitrile chemical is used alongside n-hexane to adjust polarity and achieve sharper separation profiles, especially when working with compounds of varying solubility. 

Molecular Formula and Composition

Understanding the molecular structure and composition of n-Hexane explains its behaviour as a non-polar solvent: 

  • Chemical Formula: C₆H₁₄ 
  • Molar Mass: 86.18 g/mol 
  • Molecular Structure: A linear alkane consisting of six carbon atoms and fourteen hydrogen atoms. 

Its linear configuration and non-polar nature, supported by the n-hexane formula C₆H₁₄, allow n-hexane to dissolve other non-polar compounds efficiently, a critical factor in sample preparation and solvent partitioning in HPLC analysis. 

Physical Characteristics – Appearance & Handling

The physical properties of n-Hexane support its performance in high-precision analytical workflows: 

Attribute  Specification 
Appearance  Clear, colourless liquid 
Odor  Slight petroleum-like odour 
Density  Approximately 0.66 g/cm³ at 20°C 
Evaporation Rate  Rapid evaporation leaves minimal residue 
Packaging  Amber glass bottles, aluminium cans, HDPE containers, and bulk packaging options 
Handling Notes  Highly flammable; store in cool, well-ventilated spaces away from ignition sources. Use PPE such as chemical-resistant gloves and safety eyewear. 

Its volatility and purity levels are monitored continuously to ensure stability during transport and storage. 

How is n-Hexane for HPLC Manufactured?

n-Hexane (CAS No. 110-54-3) is generally obtained from crude oil via fractional distillation, followed by advanced purification steps to meet the stringent purity requirements of HPLC-grade solvents. 

Manufacturing Steps Include: 

  1. Fractional Distillation: Crude oil is processed to isolate the hexane fraction. 
  2. Isomer Separation: The straight-chain isomer (n-Hexane) is separated from branched isomers. 
  3. Fine Purification: Advanced purification techniques remove trace moisture, non-volatile impurities, and UV-active contaminants. 
  4. Final Filtration and Packaging: Under an inert atmosphere to prevent contamination or oxidation. 

The final product is validated against HPLC suitability parameters, including UV absorbance, residue on evaporation, and water content, ensuring compatibility with advanced analytical systems.  

Industrial Applications of n-Hexane

Thanks to its low reactivity and non-polarity, n-Hexane finds use in various high-precision environments: 

Analytical Chemistry: 

  • Primary solvent for HPLC applications 
  • Used in GC (Gas Chromatography) for non-polar sample analysis 
  • Applied in sample extraction and clean-up procedures 

Pharmaceutical Testing: 

  • Solvent for active pharmaceutical ingredient (API) analysis 
  • Used in excipients profiling and drug residue testing 

Environmental Analysis: 

  • Suitable for soil and water pollutant extraction 
  • Efficient in pesticide residue testing in food samples 

Industrial Processes: 

  • Applied in solvent extraction for edible oil purification (in technical-grade forms) 
  • Used in the manufacturing of adhesives, rubber, and ink formulations (non-HPLC grades) 

In lab cleaning and gradient elution workflows, it is sometimes used alongside 2-Propanol for HPLC for better solvent range and column maintenance.
