Application

Pentane can be used as a:
  • Mobile phase in normal phase high-performance liquid chromatography (NP-HPLC) for the separation and analysis of non-polar compounds.
  • Solvent in the extraction of lipids and other non-polar substances from biological samples.
  • Purification solvent in the recrystallization of active pharmaceutical ingredients (APIs).

General description

Pentane, a highly purified solvent, is intended for use in high-performance liquid chromatography (HPLC) and other analytical applications. Its low UV absorbance and excellent volatility make it suitable for trace analysis and sample preparation across various methodologies.
