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.
N-(4-{6-oxo-5,12,14-trioxa-2-azatetracyclo[7.7.0.0^{3,7}.0^{11,15}]hexadeca-1(9),3(7),10,15-tetraen-8-yl}phenyl)acetamide (CAS 866050-84-2), molecular formula C20H16N2O5 and molecular weight 364.35 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, N-(4-{6-oxo-5,12,14-trioxa-2-azatetracyclo[7.7.0.0^{3,7}.0^{11,15}]hexadeca-1(9),3(7),10,15-tetraen-8-yl}phenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 364.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
