2-Methylthiophene Chemical Properties,Uses,Production
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.
