Deng, Ting; Tuo, Suxing; Yang, Huawu; Du, Wen; Chen, Bo; Yin, Xinqiang; Huang, Ping; Deng, Changjian; Gong, Shuguo; Lu, Hongmei; Tan, Xinliang; Zhong, Kejun published an article about the compound: 5-Methylfuran-2(3H)-one( cas:591-12-8,SMILESS:O=C1OC(C)=CC1 ).Application of 591-12-8. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:591-12-8) through the article.
In order to study the chem. composition of aerosols from heated tobacco products (HTPs) and to investigate the puff-by-puff release characteristics of aerosols from HTP samples, an online sampling device for HTP aerosols was developed by adopting a valve injection technique. Using this technique, HTP aerosols were directly introduced into gas chromatog.-mass spectrometry (GC-MS) by carrier gas (helium) through an inline heating transmission line without sample loss. The results showed that the online HTP aerosol anal. system had a stable performance and good reproducibility. The contents of acetone and 2-butanone determined in the aerosols of sample A by this method was in good accordance with the results reported by literature. With the proceeding of puffing, the releases of acetone and 2-butanone from the aerosols of sample B increased first and then decreased. This method is simple, efficient and suitable for the online anal. of the whole aerosols of HTPs and the puff-by-puff release characteristics of HTP aerosols.
I hope my short article helps more people learn about this compound(5-Methylfuran-2(3H)-one)Application of 591-12-8. Apart from the compound(591-12-8), you can read my other articles to know other related compounds.
