Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 383.25 g/mol gives 3-(4-Chlorophenyl)-5-(((4-chlorophenyl)amino)methylene)thiazolidin-4-one 1,1-dioxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(4-Chlorophenyl)-5-(((4-chlorophenyl)amino)methylene)thiazolidin-4-one 1,1-dioxide (CAS 338751-74-9) is a high-purity analytical reference standard with the molecular formula C16H12Cl2N2O3S and a molecular weight of 383.25 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(4-Chlorophenyl)-5-(((4-chlorophenyl)amino)methylene)thiazolidin-4-one 1,1-dioxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 383.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
