Chemical Structure
Description
The occurrence of 3-(Trifluoromethoxy)-4-(methylsulfonyl)bromobenzene is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(Trifluoromethoxy)-4-(methylsulfonyl)bromobenzene (CAS 731018-69-2), molecular formula C8H6BrF3O3S and molecular weight 319.10 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(Trifluoromethoxy)-4-(methylsulfonyl)bromobenzene (C8H6BrF3O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 319.10 g/mol, it falls into the moderately-high-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).
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-(Trifluoromethoxy)-4-(methylsulfonyl)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.
