Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4,6-dioxo-5-[3-(trifluoromethyl)phenyl]-3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-3-carboxylate.
CATO supplies Ethyl 4,6-dioxo-5-[3-(trifluoromethyl)phenyl]-3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-3-carboxylate (CAS 338422-50-7), a certified reference material (molecular formula C15H11F3N2O5, MW 356.25 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Ethyl 4,6-dioxo-5-[3-(trifluoromethyl)phenyl]-3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.25 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), Ethyl 4,6-dioxo-5-[3-(trifluoromethyl)phenyl]-3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-3-carboxylate 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.
