Chemical Structure
Description
As a certified reference material (CRM), 4,6-Dichloro-N-methyl-N-phenylpyrimidin-2-amine 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 4,6-Dichloro-N-methyl-N-phenylpyrimidin-2-amine (CAS 7038-66-6), a certified reference material (molecular formula C11H9Cl2N3, MW 254.12 g/mol) for analytical method development and quality control.
4,6-Dichloro-N-methyl-N-phenylpyrimidin-2-amine (C11H9Cl2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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. 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.
