| Common Name | [2,6'-Bibenzothiazole]-7-sulfonic acid, 2'-(4-aminophenyl)-6-methyl- |
|---|
| Description | [2,6'-Bibenzothiazole]-7-sulfonic acid, 2'-(4-aminophenyl)-6-methyl-, also known as 2-(4-aminophenyl)-6-methyl(2,6'-bibenzothiazole)-7-sulphonic acid or primuline free acid, belongs to the class of organic compounds known as benzothiazoles. These are organic compounds containing a benzene fused to a thiazole ring (a five-membered ring with four carbon atoms, one nitrogen atom and one sulfur atom). Based on a literature review very few articles have been published on [2,6'-Bibenzothiazole]-7-sulfonic acid, 2'-(4-aminophenyl)-6-methyl-. This compound has been identified in human blood as reported by (PMID: 31557052 ). [2,6'-bibenzothiazole]-7-sulfonic acid, 2'-(4-aminophenyl)-6-methyl- is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically [2,6'-Bibenzothiazole]-7-sulfonic acid, 2'-(4-aminophenyl)-6-methyl- 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. |
