Chemical Structure

3-Bromo-2-methylimidazo[1,2-a]pyrazine CAS 1609581-45-4 chemical structure

Description

The occurrence of 3-Bromo-2-methylimidazo[1,2-a]pyrazine is closely related to a nitrile group, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Bromo-2-methylimidazo[1,2-a]pyrazine (CAS 1609581-45-4), molecular formula C7H6BrN3 and molecular weight 212.05 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Bromo-2-methylimidazo[1,2-a]pyrazine (C7H6BrN3) is characterized by a nitrile group, 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.

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.

CATO manufactures 3-Bromo-2-methylimidazo[1,2-a]pyrazine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
