General description

Cyclohexane is a non-polar, alicyclic hydrocarbon widely recognized for its high volatility, low UV absorbance, and chemical inertness. These properties make it an ideal solvent and reference compound in various chromatographic techniques, including Gas Chromatography (GC), High-Performance Liquid Chromatography (HPLC), and Liquid Chromatography-Mass Spectrometry (LC-MS).

Application

  • Cyclohexane is extensively used in GC as a solvent for non-polar analytes.
  • Cyclohexane is compatible with LC-MS workflows, particularly in sample extraction and cleanup for non-polar analytes.
  • Its volatility and low polarity reduce background noise and improve ionization efficiency.
