Chemical Structure
Description
As a certified reference material (CRM), N-(6-Oxo-2,3,4,6-tetrahydrobenzo[f]quinoxalin-5-yl)acetamide 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.
N-(6-Oxo-2,3,4,6-tetrahydrobenzo[f]quinoxalin-5-yl)acetamide (CAS 90331-40-1) is a high-purity analytical reference standard with the molecular formula C14H13N3O2 and a molecular weight of 255.27 g/mol.
The molecular framework of N-(6-Oxo-2,3,4,6-tetrahydrobenzo[f]quinoxalin-5-yl)acetamide (C14H13N3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).
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.
