Chemical Structure
Description
2-((4-Chloro-N-phenylphenyl)sulfonamido)-N-(3-(trifluoromethyl)phenyl)acetamide (CAS 339102-58-8), molecular formula C21H16ClF3N2O3S and molecular weight 468.88 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H16ClF3N2O3S, 2-((4-Chloro-N-phenylphenyl)sulfonamido)-N-(3-(trifluoromethyl)phenyl)acetamide contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 468.88 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 2-((4-Chloro-N-phenylphenyl)sulfonamido)-N-(3-(trifluoromethyl)phenyl)acetamide 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.
