Common NameCyclen
Description1,4,7,10-tetraazacyclododecane, also known as [12]anen4 or cyclen, belongs to the class of organic compounds known as dialkylamines. These are organic compounds containing a dialkylamine group, characterized by two alkyl groups bonded to the amino nitrogen. 1,4,7,10-tetraazacyclododecane is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Cyclen is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Cyclen 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.
