Chemical Structure

2,3-Dichloro-N-(2,2,2-trifluoroethyl)quinoxaline-6-carboxamide CAS 138452-91-2 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2,3-Dichloro-N-(2,2,2-trifluoroethyl)quinoxaline-6-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

2,3-Dichloro-N-(2,2,2-trifluoroethyl)quinoxaline-6-carboxamide (CAS 138452-91-2), molecular formula C11H6Cl2F3N3O and molecular weight 324.09 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 2,3-Dichloro-N-(2,2,2-trifluoroethyl)quinoxaline-6-carboxamide 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.
