Metabolite Identification
Common Nameo-Phthalaldehyde
Descriptionphthalaldehyde, also known as OPA, belongs to the class of organic compounds known as benzoyl derivatives. These are organic compounds containing an acyl moiety of benzoic acid with the formula (C6H5CO-). Based on a literature review a significant number of articles have been published on phthalaldehyde. This compound has been identified in human blood as reported by (PMID: 31557052 ). O-phthalaldehyde is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically o-Phthalaldehyde 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.
