3-Amino-6-bromo-N-phenylpyrazine-2-carboxamide (CAS 36204-92-9), molecular formula C11H9BrN4O and molecular weight 293.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Amino-6-bromo-N-phenylpyrazine-2-carboxamide (C11H9BrN4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 3-Amino-6-bromo-N-phenylpyrazine-2-carboxamide 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.
