Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 297.49 g/mol gives 2-((6-Bromo-3-chloro-5-nitropyrazin-2-yl)amino)ethanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-((6-Bromo-3-chloro-5-nitropyrazin-2-yl)amino)ethanol (CAS 89407-82-9), a certified reference material (molecular formula C6H6BrClN4O3, MW 297.49 g/mol) for analytical method development and quality control.
The molecular framework of 2-((6-Bromo-3-chloro-5-nitropyrazin-2-yl)amino)ethanol (C6H6BrClN4O3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
