Chemical Structure
Description
The molecular framework of N-(1-(4-Methoxyphenyl)-5-oxopyrrolidin-3-yl)azepane-1-carboxamide (C18H25N3O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies N-(1-(4-Methoxyphenyl)-5-oxopyrrolidin-3-yl)azepane-1-carboxamide (CAS 877640-15-8), a certified reference material (molecular formula C18H25N3O3, MW 331.41 g/mol) for analytical method development and quality control.
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.
