Chemical Structure
Description
As a certified reference material (CRM), 1-((4-Bromophenyl)sulfonyl)-4-(phenylsulfonyl)piperidine 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.
1-((4-Bromophenyl)sulfonyl)-4-(phenylsulfonyl)piperidine (CAS 1705554-93-3) is a high-purity analytical reference standard with the molecular formula C17H18BrNO4S2 and a molecular weight of 444.36 g/mol.
The molecular framework of 1-((4-Bromophenyl)sulfonyl)-4-(phenylsulfonyl)piperidine (C17H18BrNO4S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
