Chemical Structure
Description
n-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1h-pyrazol-4-yl)-2,6-difluorobenzamide (CAS 356569-20-5), molecular formula C18H15F2N3O2 and molecular weight 343.33 g/mol, is a CATO reference standard with documented purity and traceability.
n-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1h-pyrazol-4-yl)-2,6-difluorobenzamide (C18H15F2N3O2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), n-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1h-pyrazol-4-yl)-2,6-difluorobenzamide 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.
