Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 2-(4-(3-(4-chlorophenyl)ureido)phenoxy)benzoate.
CATO supplies Methyl 2-(4-(3-(4-chlorophenyl)ureido)phenoxy)benzoate (CAS 865660-46-4), a certified reference material (molecular formula C21H17ClN2O4, MW 396.82 g/mol) for analytical method development and quality control.
Methyl 2-(4-(3-(4-chlorophenyl)ureido)phenoxy)benzoate (C21H17ClN2O4) contains a flavonoid 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. 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), Methyl 2-(4-(3-(4-chlorophenyl)ureido)phenoxy)benzoate 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.
