(5E)-3-(4-Chlorophenyl)-5-[(3-chlorophenyl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-one CAS 292169-34-7

Description

(5E)-3-(4-Chlorophenyl)-5-[(3-chlorophenyl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-one (CAS 292169-34-7) is a high-purity analytical reference standard with the molecular formula C16H9Cl2NOS2 and a molecular weight of 366.28 g/mol.

(5E)-3-(4-Chlorophenyl)-5-[(3-chlorophenyl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-one (C16H9Cl2NOS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
