2-Amino-5-bromo-3-(dimethylamino)pyrazine CAS 89641-34-9

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.

2-Amino-5-bromo-3-(dimethylamino)pyrazine (CAS 89641-34-9), molecular formula C6H9BrN4 and molecular weight 217.07 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, bromine substitution, an aromatic ring system, 2-Amino-5-bromo-3-(dimethylamino)pyrazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

As a certified reference material (CRM), 2-Amino-5-bromo-3-(dimethylamino)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.
