Compared with other compounds in its class, the molecular weight of 180.05 g/mol gives 2-Amino-5-bromopyrazine 5-bromo-pyrazin-2-ylamine 5-bromopyrazin-2-amine 2-amino-5-bromo-pyrazine 5-bromo-2-pyrazinamine 2-bromo-5-aminopyrazine 5-bromopyrazin-2-ylamine 59489-71-3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Amino-5-bromopyrazine 5-bromo-pyrazin-2-ylamine 5-bromopyrazin-2-amine 2-amino-5-bromo-pyrazine 5-bromo-2-pyrazinamine 2-bromo-5-aminopyrazine 5-bromopyrazin-2-ylamine 59489-71-3 (CAS 59489-71-3), molecular formula C4H10BrN3 and molecular weight 180.05 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Amino-5-bromopyrazine 5-bromo-pyrazin-2-ylamine 5-bromopyrazin-2-amine 2-amino-5-bromo-pyrazine 5-bromo-2-pyrazinamine 2-bromo-5-aminopyrazine 5-bromopyrazin-2-ylamine 59489-71-3 (C4H10BrN3) is characterized by 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
