Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4Z)-4-[2-(2,4-Dichlorophenoxy)-1-(dimethylamino)ethylidene]-2-phenyl-4,5-dihydro-1,3-oxazol-5-one.
(4Z)-4-[2-(2,4-Dichlorophenoxy)-1-(dimethylamino)ethylidene]-2-phenyl-4,5-dihydro-1,3-oxazol-5-one (CAS 866010-30-2), molecular formula C19H16Cl2N2O3 and molecular weight 391.25 g/mol, is a CATO reference standard with documented purity and traceability.
(4Z)-4-[2-(2,4-Dichlorophenoxy)-1-(dimethylamino)ethylidene]-2-phenyl-4,5-dihydro-1,3-oxazol-5-one (C19H16Cl2N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (4Z)-4-[2-(2,4-Dichlorophenoxy)-1-(dimethylamino)ethylidene]-2-phenyl-4,5-dihydro-1,3-oxazol-5-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
