N'-methyl-N'-(3-phenyl-6-(trifluoromethyl)-1,2,4-triazin-5-yl)pentanehydrazide (CAS 672951-07-4), molecular formula C16H18F3N5O and molecular weight 353.34 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 substitution, N'-methyl-N'-(3-phenyl-6-(trifluoromethyl)-1,2,4-triazin-5-yl)pentanehydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 353.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), N'-methyl-N'-(3-phenyl-6-(trifluoromethyl)-1,2,4-triazin-5-yl)pentanehydrazide 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.
