Chemical Structure
Description
The occurrence of (5E)-3-(2-Chlorophenyl)-5-({4-[(3,4-dichlorophenyl)methoxy]-3-nitrophenyl}methylidene)-2-sulfanylidene-1,3-thiazolidin-4-one is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (5E)-3-(2-Chlorophenyl)-5-({4-[(3,4-dichlorophenyl)methoxy]-3-nitrophenyl}methylidene)-2-sulfanylidene-1,3-thiazolidin-4-one (CAS 329779-79-5), a certified reference material (molecular formula C23H13Cl3N2O4S2, MW 551.85 g/mol) for analytical method development and quality control.
(5E)-3-(2-Chlorophenyl)-5-({4-[(3,4-dichlorophenyl)methoxy]-3-nitrophenyl}methylidene)-2-sulfanylidene-1,3-thiazolidin-4-one (C23H13Cl3N2O4S2) contains a flavonoid core, 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
