2,5-Dimethylthiophene (cas: 638-02-8) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. It has been used as a raw material for the synthesis of biologically active structures and is found in pharmaceuticals such as leukotriene synthesis inhibitors and antifungals, as well as in many natural products.Safety of 2,5-Dimethylthiophene

Extraction and identification of volatile oil from Chinese chives with GC-MS was written by Li, Shali;Xu, Shuai;Su, Ying;Wang, Lihong;Xu, Yue;Liu, Yang. And the article was included in Shipin Keji in 2019.Safety of 2,5-Dimethylthiophene The following contents are mentioned in the article:

Objective: To extract and analyze the volatile components of Chinese chives in the above ground part, and to provide the basis for the development and utilization of Chinese chive. Method: The process of extracting the volatile oil from Chinese chives by steam distillation was determined by orthogonal test, and its chem. constituents were identified by gas chromatog.-mass spectrometry anal. Result: The optimum extraction conditions of volatile oil from Chinese chives were as follows: solid-liquid ratio 1:0.5, enzyme inactivation time 30 min, ultrasonic time 40 min, distillation time 6 h. Under this condition, the extraction rate of volatile oil was 0.0388%. The gas chromatog.-mass spectrometry result showed that 31 and 30 chem. constituents were identified by enzymic hydrolysis and non-enzymic hydrolysis of volatile oil of Chinese chives, resp. The contents of sulfur compounds account for 88.18% and 87.52% of the total amount resp. The contents of 2,3-dithiabutane and 1,3-dimethyltrisulfane accounted for 60.71% and 59.65% of the total content. Conclusion: The method was simple to operate, the content of sulfur compounds in the volatile oil was high, and the enzymic hydrolysis of alliin was beneficial to increase the sulfur content in the volatile oil of Chinese chives. This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8Safety of 2,5-Dimethylthiophene).
