Chemical Structure
Description
As a certified reference material (CRM), 6-Bromo-8-methoxyimidazo[1,2-a]pyrazine 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.
6-Bromo-8-methoxyimidazo[1,2-a]pyrazine (CAS 63744-25-2), molecular formula C7H6BrN3O and molecular weight 228.05 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-8-methoxyimidazo[1,2-a]pyrazine (C7H6BrN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
