CATO supplies 4-[(5Z)-5-[(4-Nitrophenyl)methylidene]-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]-4-azatricyclo[5.2.1.0^{2,6}]dec-8-ene-3,5-dione (CAS 477766-82-8), a certified reference material (molecular formula C19H13N3O5S2, MW 427.45 g/mol) for analytical method development and quality control.

The molecular framework of 4-[(5Z)-5-[(4-Nitrophenyl)methylidene]-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]-4-azatricyclo[5.2.1.0^{2,6}]dec-8-ene-3,5-dione (C19H13N3O5S2) 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 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.
