1-(2-((3-Cyclopropyl-1,2,4-oxadiazol-5-yl)methyl)phenyl)-3-(2-fluorophenyl)urea (CAS 1797138-77-2), molecular formula C19H17FN4O2 and molecular weight 352.36 g/mol, is a CATO reference standard with documented purity and traceability.

1-(2-((3-Cyclopropyl-1,2,4-oxadiazol-5-yl)methyl)phenyl)-3-(2-fluorophenyl)urea (C19H17FN4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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), 1-(2-((3-Cyclopropyl-1,2,4-oxadiazol-5-yl)methyl)phenyl)-3-(2-fluorophenyl)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.
