Metabolite Identification

Common Name

xi-4,5-Dihydro-2,4(5)-dimethyl-1H-imidazole

Description

xi-4,5-Dihydro-2,4(5)-dimethyl-1H-imidazole belongs to the class of organic compounds known as imidolactams. These are cyclic organooxygen compounds containing the structure RC(=N)N where the central carbon atom and one of the linked nitrogen atoms are part of the same ring( R here is an organyl group). They can also be viewed as analogs of lactams where the oxygen atom is replaced by a nitrogen atom. xi-4,5-Dihydro-2,4(5)-dimethyl-1H-imidazole has been detected, but not quantified in, fishes. This could make XI-4,5-dihydro-2,4(5)-dimethyl-1H-imidazole a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on xi-4,5-Dihydro-2,4(5)-dimethyl-1H-imidazole.
