Chemical Structure
Description
As a certified reference material (CRM), 2-Amino-3-methyl-3H-imidazo[4,5-f]quinoxaline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 2-Amino-3-methyl-3H-imidazo[4,5-f]quinoxaline (CAS 108354-47-8), a certified reference material (molecular formula C10H9N5, MW 199.21 g/mol) for analytical method development and quality control.
The molecular framework of 2-Amino-3-methyl-3H-imidazo[4,5-f]quinoxaline (C10H9N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
