Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-(Diethylamino)-N-(4-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)phenyl)-2-oxo-2H-chromene-3-carboxamide.
7-(Diethylamino)-N-(4-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)phenyl)-2-oxo-2H-chromene-3-carboxamide (CAS 160291-55-4), molecular formula C24H21N3O5 and molecular weight 431.44 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, 7-(Diethylamino)-N-(4-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)phenyl)-2-oxo-2H-chromene-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 431.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
