애플리케이션

4-Methyl-3-penten-2-one may be used as a reference standard for the determination of 4-methyl-3-penten-2-one in Irish beef meats by gas chromatography-olfactometry (GC-O),[2] in human urine by static headspace extraction followed by analysis using GC with mass spectrometry (MS),[3] in caja-umbu (Spondias sp.) fruits by GC-MS[4] and in wild gilthead sea bream (Sparus aurata) by simultaneous distillation-extraction (SDE) followed by analysis using GC with flame ionization detector (FID) as well as GC-MS.[5]
