Chemical Structure

5-Bromo-6-chloro-pyrazin-2-amine CAS 173253-42-4 chemical structure

Description

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.

CATO supplies 5-Bromo-6-chloro-pyrazin-2-amine (CAS 173253-42-4), a certified reference material (molecular formula C4H9BrClN3, MW 214.49 g/mol) for analytical method development and quality control.

Owing to chlorine/bromine substitution, 5-Bromo-6-chloro-pyrazin-2-amine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
