Metabolite Identification
Common NameCyclohexanone oxime
DescriptionN-cyclohexylidenehydroxylamine belongs to the class of organic compounds known as ketoximes. These are organic compounds with the general formula RC(R')=NOH (R,R' = organyl). N-cyclohexylidenehydroxylamine is a strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Cyclohexanone oxime is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Cyclohexanone oxime is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
