Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
338772-57-9 KS-00001UIY N~1~-[3-chloro-5-(trifluoromethyl)-2-pyridinyl]-N~2~-(3-nitro-2-pyridinyl)-1,2-ethanediamine (CAS 338772-57-9) is a high-purity analytical reference standard with the molecular formula C13H11ClF3N5O2 and a molecular weight of 361.71 g/mol.
338772-57-9 KS-00001UIY N~1~-[3-chloro-5-(trifluoromethyl)-2-pyridinyl]-N~2~-(3-nitro-2-pyridinyl)-1,2-ethanediamine (C13H11ClF3N5O2) 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.
