Chemical Structure
Description
(E)-{[4-(2-methylpropyl)phenyl]methylidene}({[({[4-(trifluoromethoxy)phenyl]methyl}sulfanyl)methanimidoyl]amino})amine hydrobromide (CAS 1274948-47-8), molecular formula C20H22F3N3OSHBr and molecular weight 490.38 g/mol, is a CATO reference standard with documented purity and traceability.
(E)-{[4-(2-methylpropyl)phenyl]methylidene}({[({[4-(trifluoromethoxy)phenyl]methyl}sulfanyl)methanimidoyl]amino})amine hydrobromide (C20H22F3N3OSHBr) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
