As a certified reference material (CRM), 3-(3-Chlorophenyl)-1,1-dimethylurea 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 3-(3-Chlorophenyl)-1,1-dimethylurea (CAS 587-34-8), a certified reference material (molecular formula C9H11ClN2O, MW 198.65 g/mol) for analytical method development and quality control.
3-(3-Chlorophenyl)-1,1-dimethylurea (C9H11ClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, 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.
