Chemical Structure
Description
The occurrence of (5Z)-3-Methyl-5-[(2E)-3-phenylprop-2-en-1-ylidene]-1,3-thiazolidine-2,4-dione is closely related to a nitrogen-containing heterocyclic scaffold, 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.
(5Z)-3-Methyl-5-[(2E)-3-phenylprop-2-en-1-ylidene]-1,3-thiazolidine-2,4-dione (CAS 366824-34-2), molecular formula C13H11NO2S and molecular weight 245.30 g/mol, is a CATO reference standard with documented purity and traceability.
(5Z)-3-Methyl-5-[(2E)-3-phenylprop-2-en-1-ylidene]-1,3-thiazolidine-2,4-dione (C13H11NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
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.
