Chemical Structure
Description
The molecular framework of 8-Bromo-6-chloro-3-methylimidazo[1,2-a]pyrazine (C7H5BrClN3) is characterized by a nitrile group, 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. 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).
CATO supplies 8-Bromo-6-chloro-3-methylimidazo[1,2-a]pyrazine (CAS 84066-11-5), a certified reference material (molecular formula C7H5BrClN3, MW 246.49 g/mol) for analytical method development and quality control.
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.
