(5E)-3-(4-Chlorophenyl)-5-{[(4-chlorophenyl)amino]methylidene}-4-oxo-1,3-thiazolidin-1-ium-1-olate CAS 338752-82-2

Description

Compared with other compounds in its class, the molecular weight of 367.25 g/mol gives (5E)-3-(4-Chlorophenyl)-5-{[(4-chlorophenyl)amino]methylidene}-4-oxo-1,3-thiazolidin-1-ium-1-olate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(5E)-3-(4-Chlorophenyl)-5-{[(4-chlorophenyl)amino]methylidene}-4-oxo-1,3-thiazolidin-1-ium-1-olate (CAS 338752-82-2), molecular formula C16H12Cl2N2O2S and molecular weight 367.25 g/mol, is a CATO reference standard with documented purity and traceability.

(5E)-3-(4-Chlorophenyl)-5-{[(4-chlorophenyl)amino]methylidene}-4-oxo-1,3-thiazolidin-1-ium-1-olate (C16H12Cl2N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
