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.
1-((5-Bromo-2-(trifluoromethoxy)phenyl)sulfonyl)piperidin-4-one (CAS 1704065-49-5) is a high-purity analytical reference standard with the molecular formula C12H11BrF3NO4S and a molecular weight of 402.18 g/mol.
1-((5-Bromo-2-(trifluoromethoxy)phenyl)sulfonyl)piperidin-4-one (C12H11BrF3NO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), 1-((5-Bromo-2-(trifluoromethoxy)phenyl)sulfonyl)piperidin-4-one 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.
