Description
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.
3-[(1E)-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]hydrazin-1-ylidene}methyl]-4-hydroxy-6-methyl-2H-pyran-2-one; dimethylamine (CAS 1798395-69-3) is a high-purity analytical reference standard with the molecular formula C13H9ClF3N3O3C2H7N and a molecular weight of 392.76 g/mol.
3-[(1E)-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]hydrazin-1-ylidene}methyl]-4-hydroxy-6-methyl-2H-pyran-2-one; dimethylamine (C13H9ClF3N3O3C2H7N) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
