Chemical Structure
Description
1,4-Diphenyl-3-(trifluoromethyl)-1,4-dihydropyridazine (C17H13F3N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
1,4-Diphenyl-3-(trifluoromethyl)-1,4-dihydropyridazine (CAS 1377791-70-2) is a high-purity analytical reference standard with the molecular formula C17H13F3N2 and a molecular weight of 302.29 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
