Chemical Structure
Description
The occurrence of 2-[(6-Acetamidopyridin-3-yl)sulfanyl]-N-(4-fluorophenyl)pyridine-3-carboxamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-[(6-Acetamidopyridin-3-yl)sulfanyl]-N-(4-fluorophenyl)pyridine-3-carboxamide (CAS 343373-13-7) is a high-purity analytical reference standard with the molecular formula C19H15FN4O2S and a molecular weight of 382.41 g/mol.
2-[(6-Acetamidopyridin-3-yl)sulfanyl]-N-(4-fluorophenyl)pyridine-3-carboxamide (C19H15FN4O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
