(E)-[(3,4-Dichlorophenyl)methoxy]({[2-(phenylsulfanyl)pyridin-3-yl]methylidene})amine (CAS 478031-08-2), molecular formula C19H14Cl2N2OS and molecular weight 389.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, (E)-[(3,4-Dichlorophenyl)methoxy]({[2-(phenylsulfanyl)pyridin-3-yl]methylidene})amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 389.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
