Metabolite Identification
Common Name4-Hydroxypenbutolol
Description4-Hydroxypenbutolol belongs to the class of organic compounds known as 4-alkoxyphenols. These are phenols that carry an alkoxy group at the 4-position of the benzene ring. Based on a literature review a significant number of articles have been published on 4-Hydroxypenbutolol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-hydroxypenbutolol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-Hydroxypenbutolol 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.
