Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-[(2-{[(4-chlorophenyl)methyl]sulfanyl}quinolin-3-yl)methylidene][(2,4-dichlorophenyl)methoxy]amine.
(E)-[(2-{[(4-chlorophenyl)methyl]sulfanyl}quinolin-3-yl)methylidene][(2,4-dichlorophenyl)methoxy]amine (CAS 478079-33-3), molecular formula C24H17Cl3N2OS and molecular weight 487.83 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)-[(2-{[(4-chlorophenyl)methyl]sulfanyl}quinolin-3-yl)methylidene][(2,4-dichlorophenyl)methoxy]amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 487.83 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
