Rapid identification of volatile compounds in sesame oil by headspace gas chromatography-mass spectrometry with calibrated lineshape isotope profile search(CLIPs) was written by Ma, Yu-song;Wang, Jing;Ai, Lian-feng;Dou, Cai-yun;Jia, Hai-tao;Yu, Meng. And the article was included in Fenxi Ceshi Xuebao in 2015.Application of 20662-84-4 This article mentions the following:
The volatile compounds in sesame oil were analyzed by headspace gas chromatog.-mass spectrometry(GC-MS) with calibrated lineshape isotope profile search(CLIPs) function integrated in Mass WorksTM software. 71 Kinds of components including pyrazines, pyrroles, pyridines, thiazoles, thiophenes, indoles, oxazoles, furans, aldehydes and phenols etc., could be identified, which accounted for 90.2% of the total normalized peak areas. Among them, aldehydes, phenols, pyrazines and furans account for 37.4%, 20.1%, 10.0% and 6.7%, resp. They were principal contributors of sesame oil flavor components. The application of CLIPs can provide the accurate mol. weight of compounds and an important basis for the low-resolution quadrupole mass spectrometer to identify the elemental composition and the structure of compound The study provided a new tech. means for the component anal. of sesame oils. In the experiment, the researchers used many compounds, for example, 2,4,5-Trimethyloxazole (cas: 20662-84-4Application of 20662-84-4).
2,4,5-Trimethyloxazole (cas: 20662-84-4) belongs to oxazolidine derivatives. Oxazolidine-based compounds have started to attract attention also in the medicinal and materials chemistry fields. In another report, the incorporation of an additional substituted oxazolidine ring over a range of new biphenylazepinium salt organocatalysts for the asymmetric epoxidation of alkenes improved enantiocontrol over the parent structures.Application of 20662-84-4
