Metabolite Identification
Common Name(R)-Myclobutanil
Description(R)-Myclobutanil, also known as systhane, belongs to the class of organic compounds known as chlorobenzenes. Chlorobenzenes are compounds containing one or more chlorine atoms attached to a benzene moiety. Based on a literature review a significant number of articles have been published on (R)-Myclobutanil. This compound has been identified in human blood as reported by (PMID: 31557052 ). (r)-myclobutanil is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (R)-Myclobutanil 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.
