Metabolite Identification

Common Name

Phthalhydrazide

Description

phthalazine-1,4-diol belongs to the class of organic compounds known as phthalazinones. Phthalazinones are compounds containing a phthalazine bearing a ketone group. Based on a literature review very few articles have been published on phthalazine-1,4-diol. This compound has been identified in human blood as reported by (PMID: 31557052 ). Phthalhydrazide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Phthalhydrazide 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.
