Description
CATO supplies 2-methoxy-N-[2-(3-methyl-2,6-dioxo-3-piperidyl)-1,3-dioxo-isoindolin-4-yl]acetamide (CAS 444288-45-3), a certified reference material (molecular formula C17H17N3O6, MW 359.33 g/mol) for analytical method development and quality control.
Structurally, 2-methoxy-N-[2-(3-methyl-2,6-dioxo-3-piperidyl)-1,3-dioxo-isoindolin-4-yl]acetamide (C17H17N3O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 359.33 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).
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.
