Chemical Structure
Description
The occurrence of 4-Oxo-2-thioxo-5-[(3,4,5-trimethoxyphenyl)methylene]-3-thiazolidinepropanoic acid is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Oxo-2-thioxo-5-[(3,4,5-trimethoxyphenyl)methylene]-3-thiazolidinepropanoic acid (CAS 306323-53-5) is a high-purity analytical reference standard with the molecular formula C16H17NO6S2 and a molecular weight of 383.44 g/mol.
The molecular framework of 4-Oxo-2-thioxo-5-[(3,4,5-trimethoxyphenyl)methylene]-3-thiazolidinepropanoic acid (C16H17NO6S2) is characterized by a flavonoid core, 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.
