3-Hexanone is a perfuming agent. It is used as a solvent. 3-Hexanone was used in a study to determine Henry?s law coefficients by combination of the equilibrium partitioning in closed systems technique in combination with solid-phase microextraction. It was used as test species in a study for quantitative determination of volatile organic compounds by chemical ionization reaction mass spectrometry. It was used to study the inhibitory activity of some aromatic and aliphatic ketones against Clostridium Botulinum spores and cells.
