Chemical Structure
Description
As a certified reference material (CRM), 1,2-Diamino-5-bromopyridin-1-ium 2,4,6-trimethylbenzenesulfonate 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 1,2-Diamino-5-bromopyridin-1-ium 2,4,6-trimethylbenzenesulfonate (CAS 1202704-57-1), a certified reference material (molecular formula C9H11O3SC5H7BrN3, MW 388.28 g/mol) for analytical method development and quality control.
The molecular framework of 1,2-Diamino-5-bromopyridin-1-ium 2,4,6-trimethylbenzenesulfonate (C9H11O3SC5H7BrN3) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
