Chemical Structure
Description
The occurrence of 3-Fluoro-4-(pentafluoroethylthio)bromobenzene is closely related to sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Fluoro-4-(pentafluoroethylthio)bromobenzene (CAS 1301739-36-5), molecular formula C8H3BrF6S and molecular weight 325.07 g/mol, is a CATO reference standard with documented purity and traceability.
3-Fluoro-4-(pentafluoroethylthio)bromobenzene (C8H3BrF6S) contains sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 3-Fluoro-4-(pentafluoroethylthio)bromobenzene 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.
