Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 257.07 g/mol gives 4-Bromo-3-(trifluoromethyl)benzenethiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Bromo-3-(trifluoromethyl)benzenethiol (CAS 1208076-57-6), a certified reference material (molecular formula C7H4BrF3S, MW 257.07 g/mol) for analytical method development and quality control.
Structurally, 4-Bromo-3-(trifluoromethyl)benzenethiol (C7H4BrF3S) contains sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 257.07 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Bromo-3-(trifluoromethyl)benzenethiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
