Application
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.
General description
3-Methyl-2(5H)-furanone (3-Methylfuran-2(5H)-one) has been synthesized in highest yield (77%) by employing α-methyl-γ- butyrolactone as starting reagent.
3-Methyl-2(5H)-furanone, a five membered conjugated lactone, is a volatile compound. Its synthesis has been reported. It is reported to be one of the predominant constituent of the flavor of pandan leaves. It is also found in Thai soy sauce, Arabica roasted coffee samples from Brazil, bio-oil from pine wood sawdust.

The tropolone-tolerant Trichoderma virens PS1-7 is a biocontrol agent against Burkholderia plantarii, causative of rice seedling blight. When exposed to catechol, this fungus dose-dependently produced carot-4-en-9,10-diol, a sesquiterpene-type autoregulatory signal molecule that promotes self-conidiation of T. virens PS1-7 mycelia. It
