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.
CATO supplies [2-(2,6-dioxo-3-piperidyl)-3-oxo-isoindolin-5-yl]methyl N-[2-fluoro-4-methyl-5-(trifluoromethoxy)phenyl]carbamate (CAS 2803881-73-2), a certified reference material (molecular formula C23H19F4N3O6, MW 509.41 g/mol) for analytical method development and quality control.
Structurally, [2-(2,6-dioxo-3-piperidyl)-3-oxo-isoindolin-5-yl]methyl N-[2-fluoro-4-methyl-5-(trifluoromethoxy)phenyl]carbamate (C23H19F4N3O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 509.41 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.
