Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-({3-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1,2-oxazol-5-yl}(phenyl)methylidene)[(2,6-dichlorophenyl)methoxy]amine.
(E)-({3-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1,2-oxazol-5-yl}(phenyl)methylidene)[(2,6-dichlorophenyl)methoxy]amine (CAS 861211-77-0), molecular formula C23H13Cl3F3N3O2 and molecular weight 526.72 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (E)-({3-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1,2-oxazol-5-yl}(phenyl)methylidene)[(2,6-dichlorophenyl)methoxy]amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 526.72 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.
As a certified reference material (CRM), (E)-({3-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1,2-oxazol-5-yl}(phenyl)methylidene)[(2,6-dichlorophenyl)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.
