| Common Name | Acetyl 4-aminosalicylic acid |
|---|
| Description | Acetyl 4-aminosalicylic acid, also known as acpas, belongs to the class of organic compounds known as acylsalicylic acids. These are o-acylated derivatives of salicylic acid. Based on a literature review a small amount of articles have been published on Acetyl 4-aminosalicylic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Acetyl 4-aminosalicylic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Acetyl 4-aminosalicylic acid 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. |
