Chemical Structure
Description
N-(4-Chlorophenyl)-3-{[(2,6-dichlorophenyl)methyl]sulfanyl}thiophene-2-carboxamide (C18H12Cl3NOS2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
N-(4-Chlorophenyl)-3-{[(2,6-dichlorophenyl)methyl]sulfanyl}thiophene-2-carboxamide (CAS 251096-91-0) is a high-purity analytical reference standard with the molecular formula C18H12Cl3NOS2 and a molecular weight of 428.78 g/mol.
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.
