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 2-Chloro-N-(4-(4-chlorophenyl)-1,2,5-oxadiazol-3-yl)benzamide (CAS 866237-86-7), a certified reference material (molecular formula C15H9Cl2N3O2, MW 334.16 g/mol) for analytical method development and quality control.
2-Chloro-N-(4-(4-chlorophenyl)-1,2,5-oxadiazol-3-yl)benzamide (C15H9Cl2N3O2) contains a nitrogen-containing heterocyclic scaffold, 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), 2-Chloro-N-(4-(4-chlorophenyl)-1,2,5-oxadiazol-3-yl)benzamide 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.
