- Abstract
2,4-dimethyl-4-phenyltetrahydrofuran is a flavoring agent that is permitted for use in food in Japan. To ensure the safety of this compound, its toxicity has been surveyed. For the safety assessment of chemicals, it is important to elucidate the abundance ratio of isomers, if they exist, because isomers can have different biological activities. For this compound, there are four potential isomers; however, no information on the abundance ratio of these isomers currently exists for the commercially available flavoring agent. In this study, the isomer abundance ratio in the commercial product was determined by quantitative 1H-NMR and GC/MS equipped with a chiral column. All four isomers existed in almost equal amounts in the commercially available product.
