Metabolite Identification
Common Name1,1-Difluoroethane
Description1,1-Difluoroethane, also known as ethylidene difluoride, belongs to the class of organic compounds known as organofluorides. Organofluorides are compounds containing a chemical bond between a carbon atom and a fluorine atom. Based on a literature review a significant number of articles have been published on 1,1-Difluoroethane. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1,1-difluoroethane is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1,1-Difluoroethane 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.
