High-Purity Nonpolar Solvent for Extraction, Chromatography, Organic Synthesis and Laboratory Use

n-Hexane is a volatile, nonpolar hydrocarbon solvent widely used in chemical synthesis, extraction, chromatography and laboratory sample preparation.

J&K Scientific supplies n-Hexane, 99% for general laboratory and research applications. For applications requiring tighter moisture control, J&K also offers HPLC, LC-MS and specialty anhydrous solvent grades.

Typical Applications

1. Liquid–Liquid Extraction

n-Hexane is widely used as a nonpolar phase in liquid–liquid extraction. It can be used to extract Hydrocarbons, Lipids, Oils, Hydrophobic organic compounds and Nonpolar reaction products.

Actual extraction efficiency depends on the compound, phase ratio, temperature and solvent system.

2. Chromatography

n-Hexane is commonly used as a mobile-phase component in normal-phase chromatography and flash chromatography. It is often combined with more polar solvents to adjust elution strength.

Typical applications include Column chromatography, Flash chromatography, Thin-layer chromatography method development, and Purification of nonpolar and moderately polar organic compounds.

3. Organic Synthesis

n-Hexane can serve as a reaction solvent, dilution solvent or workup solvent in organic chemistry. Applications may include Reaction media, Reagent dilution, Extraction after synthesis, Precipitation or washing steps and Solvent exchange.

The suitability of n-Hexane should be evaluated according to substrate solubility, reaction conditions and safety requirements.

4. Sample Preparation

n-Hexane is frequently used in analytical sample preparation where nonpolar compounds need to be isolated from complex matrices. Potential uses in Lipid extraction, Hydrocarbon extraction, Environmental sample preparation, Food and natural-product analysis and Pre-treatment prior to instrumental analysis.

5. General Laboratory Solvent

n-Hexane is also used as a general-purpose solvent for dissolving, washing or processing hydrophobic substances in laboratory workflows.
