Anwendungen & Verwendung

Verwenden

3-Methyl-2(5H)-furanone is the suitable model compound used to investigate the fragmentation mechanism of five membered lactones by electrospray ionisation tandem mass spectrometry and also to study the airway irritation of isoprene, isoprene/ozone, and isoprene/ozone/nitrogen dioxide mixture.
