Chemical Structure
Description
1-Nitroso-4-oxo-6-(trifluoromethyl)-1,4-dihydroquinoline-3-carboxylic acid (CAS CATO-C3D-263040), molecular formula C11H5F3N2O4 and molecular weight 286.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Nitroso-4-oxo-6-(trifluoromethyl)-1,4-dihydroquinoline-3-carboxylic acid (C11H5F3N2O4) 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 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 286.16 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
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.
