Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, (E)-[1-(4-Bromophenyl)-2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenoxy)ethylidene][(3-chloro-2-fluorophenyl)methoxy]amine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 642.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
(E)-[1-(4-Bromophenyl)-2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenoxy)ethylidene][(3-chloro-2-fluorophenyl)methoxy]amine (CAS 339020-18-7), molecular formula C28H19BrCl2F4N2O2 and molecular weight 642.27 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (E)-[1-(4-Bromophenyl)-2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenoxy)ethylidene][(3-chloro-2-fluorophenyl)methoxy]amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
