Common Name

2,3,5,6-Tetramethyl-1H,7H-pyrazolo[1,2-a]pyrazole-1,7-dione

Description

2,3,5,6-Tetramethyl-1H,7H-pyrazolo[1,2-a]pyrazole-1,7-dione, also known as bimane, belongs to the class of organic compounds known as pyrazolopyrazoles. These are polycyclic aromatic compounds containing to pyrazole rings fused to each other. Pyrazole is 5-membered ring consisting of three carbon atoms and two adjacent nitrogen centers. Based on a literature review very few articles have been published on 2,3,5,6-Tetramethyl-1H,7H-pyrazolo[1,2-a]pyrazole-1,7-dione. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2,3,5,6-tetramethyl-1h,7h-pyrazolo[1,2-a]pyrazole-1,7-dione is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,3,5,6-Tetramethyl-1H,7H-pyrazolo[1,2-a]pyrazole-1,7-dione 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.
