Chemical Structure

(E)-5-((Dimethylamino)methylene)-3-(4-methoxyphenyl)thiazolidin-4-one 1,1-dioxide CAS 1164536-98-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 296.34 g/mol gives (E)-5-((Dimethylamino)methylene)-3-(4-methoxyphenyl)thiazolidin-4-one 1,1-dioxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-5-((Dimethylamino)methylene)-3-(4-methoxyphenyl)thiazolidin-4-one 1,1-dioxide (CAS 1164536-98-4), molecular formula C13H16N2O4S and molecular weight 296.34 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-5-((Dimethylamino)methylene)-3-(4-methoxyphenyl)thiazolidin-4-one 1,1-dioxide (C13H16N2O4S) is characterized by a nitrogen-containing heterocyclic scaffold, 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.

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.
