Description
8-(2-Methoxyphenyl)-5,12,14-trioxa-2-azatetracyclo[7.7.0.0^{3,7}.0^{11,15}]hexadeca-1(9),3(7),10,15-tetraen-6-one (CAS 866050-82-0), molecular formula C19H15NO5 and molecular weight 337.33 g/mol, is a CATO reference standard with documented purity and traceability.
8-(2-Methoxyphenyl)-5,12,14-trioxa-2-azatetracyclo[7.7.0.0^{3,7}.0^{11,15}]hexadeca-1(9),3(7),10,15-tetraen-6-one (C19H15NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
