1H,3H,3aH,4H,9H,9aH-2$l^{6},4,9-thieno[3,4-b]quinoxaline-2,2-dione CAS 56714-11-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 224.28 g/mol gives 1H,3H,3aH,4H,9H,9aH-2$l^{6},4,9-thieno[3,4-b]quinoxaline-2,2-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1H,3H,3aH,4H,9H,9aH-2$l^{6},4,9-thieno[3,4-b]quinoxaline-2,2-dione (CAS 56714-11-5), a certified reference material (molecular formula C10H12N2O2S, MW 224.28 g/mol) for analytical method development and quality control.

The molecular framework of 1H,3H,3aH,4H,9H,9aH-2$l^{6},4,9-thieno[3,4-b]quinoxaline-2,2-dione (C10H12N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.

As a certified reference material (CRM), 1H,3H,3aH,4H,9H,9aH-2$l^{6},4,9-thieno[3,4-b]quinoxaline-2,2-dione 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.
