Compared with other compounds in its class, the molecular weight of 429.32 g/mol gives 3-((3,4-Dichlorobenzyl)oxy)-N-phenylthieno[2,3-b]pyridine-2-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-((3,4-Dichlorobenzyl)oxy)-N-phenylthieno[2,3-b]pyridine-2-carboxamide (CAS 338757-00-9), a certified reference material (molecular formula C21H14Cl2N2O2S, MW 429.32 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 3-((3,4-Dichlorobenzyl)oxy)-N-phenylthieno[2,3-b]pyridine-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 429.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
