Chemical Structure
Description
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.
n-(3,5-Bis(trifluoromethyl)phenyl)-4-bromobenzenesulfonamide (CAS 712298-33-4) is a high-purity analytical reference standard with the molecular formula C14H8BrF6NO2S and a molecular weight of 448.18 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, n-(3,5-Bis(trifluoromethyl)phenyl)-4-bromobenzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 448.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), n-(3,5-Bis(trifluoromethyl)phenyl)-4-bromobenzenesulfonamide 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.
