Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-(3-Chlorophenyl)-3-[3-(tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]urea (CAS 874302-01-9), a certified reference material (molecular formula C19H22BClN2O3, MW 372.65 g/mol) for analytical method development and quality control.
1-(3-Chlorophenyl)-3-[3-(tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]urea (C19H22BClN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), 1-(3-Chlorophenyl)-3-[3-(tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]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.
