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 3-(2-(Dimethylamino)ethoxy)-6-methyl-1-(3-(trifluoromethyl)phenyl)pyridazin-4(1H)-one (CAS 146824-81-9), a certified reference material (molecular formula C16H18F3N3O2, MW 341.33 g/mol) for analytical method development and quality control.
Structurally, 3-(2-(Dimethylamino)ethoxy)-6-methyl-1-(3-(trifluoromethyl)phenyl)pyridazin-4(1H)-one (C16H18F3N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 341.33 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
