Chemical Structure
Description
(E)-({6-[(4-chlorophenyl)sulfanyl]pyridin-3-yl}methylidene)(methoxy)amine (CAS 338966-93-1) is a high-purity analytical reference standard with the molecular formula C13H11ClN2OS and a molecular weight of 278.76 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, (E)-({6-[(4-chlorophenyl)sulfanyl]pyridin-3-yl}methylidene)(methoxy)amine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 278.76 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.
