CATO supplies 320421-99-6 4-bromo-N'-methyl-N'-[2-(trifluoromethyl)-4-quinazolinyl]benzenesulfonohydrazide KS-0000314D (CAS 320421-99-6), a certified reference material (molecular formula C16H12BrF3N4O2S, MW 461.26 g/mol) for analytical method development and quality control.
The molecular framework of 320421-99-6 4-bromo-N'-methyl-N'-[2-(trifluoromethyl)-4-quinazolinyl]benzenesulfonohydrazide KS-0000314D (C16H12BrF3N4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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.
