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)-3-phenyl-2-(3-(trifluoromethyl)styryl)quinazolin-4(3H)-one.
CATO supplies (E)-3-phenyl-2-(3-(trifluoromethyl)styryl)quinazolin-4(3H)-one (CAS 338751-43-2), a certified reference material (molecular formula C23H15F3N2O, MW 392.37 g/mol) for analytical method development and quality control.
(E)-3-phenyl-2-(3-(trifluoromethyl)styryl)quinazolin-4(3H)-one (C23H15F3N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-phenyl-2-(3-(trifluoromethyl)styryl)quinazolin-4(3H)-one 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.
