Metabolite Identification
Common NameTetramethylrhodamine isothiocyanate
DescriptionTetramethylrhodamine isothiocyanate, also known as TRITC or rhodamine tetramethylisothiocyanate, belongs to the class of organic compounds known as xanthenes. These are polycyclic aromatic compounds containing a xanthene moiety, which consists of two benzene rings joined to each other by a pyran ring. Based on a literature review a significant number of articles have been published on Tetramethylrhodamine isothiocyanate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Tetramethylrhodamine isothiocyanate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Tetramethylrhodamine isothiocyanate 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.
