Description
As a certified reference material (CRM), 5-(((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)amino)methyl)-N'-(cyclopropanecarbonyl)-4,5-dihydroisoxazole-3-carbohydrazide 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.
5-(((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)amino)methyl)-N'-(cyclopropanecarbonyl)-4,5-dihydroisoxazole-3-carbohydrazide (CAS 338399-36-3), molecular formula C15H15ClF3N5O3 and molecular weight 405.76 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 5-(((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)amino)methyl)-N'-(cyclopropanecarbonyl)-4,5-dihydroisoxazole-3-carbohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 405.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
