General description

Cyclopentanone is one of the industrially important compounds employed in the synthesis of fungicides, pharmaceuticals, rubber chemicals and perfume products.

Application

Cyclopentanone may be used as a reference standard for the determination of cyclopentanone in:
  • Pyrolysis oil samples by gas chromatography with flame ionization detector (GC-FID) as well as two-dimensional GC with time-of-flight mass spectrometry (GC×GC-TOFMS).
  • Brazilian sugarcane spirits and rum by high-performance liquid chromatography (HPLC) with ultraviolet-visible (UV-Vis) diode array detector (DAD).
  • Crude and hydrotreated bio-oils obtained from various biomass resources by GC×GC-FID as well as GC×GC-TOF MS.
  • Indoor air samples of semiconductor foundries by multisorbent adsorption/thermal desorption combined with GC-MS.
