Metabolite Identification
Common NameS-Ethyl dipropylthiocarbamate
DescriptionDipropylcarbamothioic acid S-ethyl ester, also known as S-ethyl dipropylthiocarbamate or eptam, belongs to the class of organic compounds known as thiocarbamic acid derivatives. These are organic compounds containing a functional group with the general structure OC(=S)NR2 or SC(=O)NR2. Based on a literature review a significant number of articles have been published on Dipropylcarbamothioic acid S-ethyl ester. This compound has been identified in human blood as reported by (PMID: 31557052 ). S-ethyl dipropylthiocarbamate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically S-Ethyl dipropylthiocarbamate 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.
