CATO supplies 2-Bromo-N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-4-nitroaniline (CAS 220301-84-8), a certified reference material (molecular formula C8H3BrClN3O2S2, MW 352.62 g/mol) for analytical method development and quality control.
The molecular framework of 2-Bromo-N-(4-chloro-5H-1,2,3-dithiazol-5-ylidene)-4-nitroaniline (C8H3BrClN3O2S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/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).
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.
