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 5-Bromo-2-(2,5-dimethyl-1H-pyrrol-1-yl)thiazole (CAS 918792-84-4), a certified reference material (molecular formula C9H9BrN2S, MW 257.15 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromo-2-(2,5-dimethyl-1H-pyrrol-1-yl)thiazole (C9H9BrN2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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.
As a certified reference material (CRM), 5-Bromo-2-(2,5-dimethyl-1H-pyrrol-1-yl)thiazole 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.
