Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-[4-Chloro-3-(trifluoromethyl)phenyl]-2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}acetamide.
CATO supplies N-[4-Chloro-3-(trifluoromethyl)phenyl]-2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}acetamide (CAS 1105207-34-8), a certified reference material (molecular formula C21H13ClF3N3O2S, MW 463.86 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, N-[4-Chloro-3-(trifluoromethyl)phenyl]-2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 463.86 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), N-[4-Chloro-3-(trifluoromethyl)phenyl]-2-{4-oxo-7-phenyl-3H,4H-thieno[3,2-d]pyrimidin-3-yl}acetamide 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.
