Chemical Structure
Description
As a certified reference material (CRM), 1-(2,4-Dichlorophenyl)Urea 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 1-(2,4-Dichlorophenyl)Urea (CAS 5428-50-2), a certified reference material (molecular formula C7H6Cl2N2O, MW 205.04 g/mol) for analytical method development and quality control.
1-(2,4-Dichlorophenyl)Urea (C7H6Cl2N2O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
