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.
CATO supplies N-(3-bromo-5-oxo-4-phenoxy-2,5-dihydrofuran-2-yl)-2-methylbenzenesulfonamide (CAS 126956-35-2), a certified reference material (molecular formula C17H14BrNO5S, MW 424.27 g/mol) for analytical method development and quality control.
The molecular framework of N-(3-bromo-5-oxo-4-phenoxy-2,5-dihydrofuran-2-yl)-2-methylbenzenesulfonamide (C17H14BrNO5S) 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. 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).
As a certified reference material (CRM), N-(3-bromo-5-oxo-4-phenoxy-2,5-dihydrofuran-2-yl)-2-methylbenzenesulfonamide 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.
