Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(2,4-Dichlorophenyl)-3-(4-(2,4-dichlorophenyl)thiazol-2-yl)-5-methylthiazolidin-4-one (CAS 866048-99-9), molecular formula C19H12Cl4N2OS2 and molecular weight 490.25 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H12Cl4N2OS2, 2-(2,4-Dichlorophenyl)-3-(4-(2,4-dichlorophenyl)thiazol-2-yl)-5-methylthiazolidin-4-one contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 490.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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.
