Chemical Structure
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.
(4E)-4-[(2H-1,3-Benzodioxol-5-yl)methylidene]-2-(2,6-dimethylmorpholin-4-yl)-4,5-dihydro-1H-imidazol-5-one (CAS 866142-91-8), molecular formula C17H19N3O4 and molecular weight 329.35 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (4E)-4-[(2H-1,3-Benzodioxol-5-yl)methylidene]-2-(2,6-dimethylmorpholin-4-yl)-4,5-dihydro-1H-imidazol-5-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
