Description2-(diethylamino)ethyl 2,2-diphenylpentanoate belongs to the class of organic compounds known as diphenylmethanes. Diphenylmethanes are compounds containing a diphenylmethane moiety, which consists of a methane wherein two hydrogen atoms are replaced by two phenyl groups. Based on a literature review very few articles have been published on 2-(diethylamino)ethyl 2,2-diphenylpentanoate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Proadifen is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Proadifen 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.
