Chemical Structure
Description
1-Benzyloxy-3-(4-bromo-3-chlorophenyl)urea (CAS 845879-19-8), molecular formula C14H12BrClN2O2 and molecular weight 355.61 g/mol, is a CATO reference standard with documented purity and traceability.
1-Benzyloxy-3-(4-bromo-3-chlorophenyl)urea (C14H12BrClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Benzyloxy-3-(4-bromo-3-chlorophenyl)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.
