5-(8-Ethoxy-2-oxo-2H-chromen-3-yl)-8-thia-4,6-diazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5-trien-3-one CAS 313985-92-1 chemical structure

Description

As a certified reference material (CRM), 5-(8-Ethoxy-2-oxo-2H-chromen-3-yl)-8-thia-4,6-diazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5-trien-3-one 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 5-(8-Ethoxy-2-oxo-2H-chromen-3-yl)-8-thia-4,6-diazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5-trien-3-one (CAS 313985-92-1), a certified reference material (molecular formula C21H18N2O4S, MW 394.44 g/mol) for analytical method development and quality control.

The molecular framework of 5-(8-Ethoxy-2-oxo-2H-chromen-3-yl)-8-thia-4,6-diazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5-trien-3-one (C21H18N2O4S) is characterized by a flavonoid core, an amide group, a sulfone 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
