Metabolite Identification
Common NameTert-Butyl carbamate
Description(tert-butoxy)carboximidic acid belongs to the class of organic compounds known as carbamate esters. Carbamate esters are compounds containing an ester of carbamic acid with the general structure R2NC(=O)OR' (R' not H). They are esters of carbamic acids. Based on a literature review very few articles have been published on (tert-butoxy)carboximidic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Tert-butyl carbamate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Tert-Butyl carbamate 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.
