Description
As a certified reference material (CRM), N-(5,7-Dibromoquinolin-8-yl)-4-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.
CATO supplies N-(5,7-Dibromoquinolin-8-yl)-4-methylbenzenesulfonamide (CAS 21868-75-7), a certified reference material (molecular formula C16H12Br2N2O2S, MW 456.15 g/mol) for analytical method development and quality control.
Structurally, N-(5,7-Dibromoquinolin-8-yl)-4-methylbenzenesulfonamide (C16H12Br2N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 456.15 g/mol, it falls into the moderately-high-molecular-weight range. 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.
