Chemical Structure
Description
N-[4-(4-Chlorophenyl)-1,3-thiazol-2-yl]-2-[(2,5-dichlorophenyl)sulfanyl]acetamide (CAS 338959-63-0) is a high-purity analytical reference standard with the molecular formula C17H11Cl3N2OS2 and a molecular weight of 429.77 g/mol.
N-[4-(4-Chlorophenyl)-1,3-thiazol-2-yl]-2-[(2,5-dichlorophenyl)sulfanyl]acetamide (C17H11Cl3N2OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
