Chemical Structure
Description
As a certified reference material (CRM), (E)-N'-[(4-Chlorophenyl)methoxy]-N-{thieno[2,3-d]pyrimidin-4-yl}methanimidamide 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.
CATO supplies (E)-N'-[(4-Chlorophenyl)methoxy]-N-{thieno[2,3-d]pyrimidin-4-yl}methanimidamide (CAS 477846-25-6), a certified reference material (molecular formula C14H11ClN4OS, MW 318.78 g/mol) for analytical method development and quality control.
(E)-N'-[(4-Chlorophenyl)methoxy]-N-{thieno[2,3-d]pyrimidin-4-yl}methanimidamide (C14H11ClN4OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
