| Description | Triethylamine, also known as (C2H5)3N or NET3, belongs to the class of organic compounds known as trialkylamines. These are organic compounds containing a trialkylamine group, characterized by exactly three alkyl groups bonded to the amino nitrogen. Triethylamine is an ammoniacal and fishy tasting compound. Triethylamine is found, on average, in the highest concentration within grape wine. This could make triethylamine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Triethylamine. |
