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.
CATO supplies (5E)-3-(4-Chlorophenyl)-5-[(2,3-dihydro-1,4-benzodioxin-6-yl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-one (CAS 882082-97-5), a certified reference material (molecular formula C18H12ClNO3S2, MW 389.88 g/mol) for analytical method development and quality control.
The molecular framework of (5E)-3-(4-Chlorophenyl)-5-[(2,3-dihydro-1,4-benzodioxin-6-yl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-one (C18H12ClNO3S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
As a certified reference material (CRM), (5E)-3-(4-Chlorophenyl)-5-[(2,3-dihydro-1,4-benzodioxin-6-yl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-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.
