| | 2-Methylthiophene Usage And Synthesis |
| Chemical Properties | clear colorless to slightly yellow liquid | | Uses | 2-Methylthiophene, is used as a flavoring agent that naturally occurs in grilled and roasted beef, papaya, cooked shrimp, whiskey, and in trace amounts in roasted chicken; | | Definition | ChEBI: 2-methylthiophene is a member of the class of thiophenes that is thiophene in which the hydrogen atom at position 2 is substituted by a methyl group. It has a role as a flavouring agent and a Maillard reaction product. It is a member of thiophenes and a volatile organic compound. It is functionally related to a thiophene. | | Production Methods | 2-Methylthiophene is commercially produced
to 98 wt% purity by VP cyclization. | | Application | 2-Methylthiophene is a feasible raw material for the production
of several of the important 2-substituted thiophenes. It may be used to manufacture 2-chloromethylthiophene (2-thenyl chloride), but this
and further syntheses must be completed in situ,
because of its instability. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 14, p. 638, 1949 DOI: 10.1021/jo01156a016
