N-(5,7-Dioxo-5,7-dihydro-6H-dibenzo[c,e]azepin-6-yl)benzamide CAS 923131-86-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 342.35 g/mol gives N-(5,7-Dioxo-5,7-dihydro-6H-dibenzo[c,e]azepin-6-yl)benzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(5,7-Dioxo-5,7-dihydro-6H-dibenzo[c,e]azepin-6-yl)benzamide (CAS 923131-86-6), molecular formula C21H14N2O3 and molecular weight 342.35 g/mol, is a CATO reference standard with documented purity and traceability.

N-(5,7-Dioxo-5,7-dihydro-6H-dibenzo[c,e]azepin-6-yl)benzamide (C21H14N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
