N-[2-(2,6-dioxo-3-piperidyl)-1,3-dioxo-isoindolin-4-yl]-2-ethoxy-acetamide CAS 444288-18-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-[2-(2,6-dioxo-3-piperidyl)-1,3-dioxo-isoindolin-4-yl]-2-ethoxy-acetamide.

CATO supplies N-[2-(2,6-dioxo-3-piperidyl)-1,3-dioxo-isoindolin-4-yl]-2-ethoxy-acetamide (CAS 444288-18-0), a certified reference material (molecular formula C17H17N3O6, MW 359.33 g/mol) for analytical method development and quality control.

N-[2-(2,6-dioxo-3-piperidyl)-1,3-dioxo-isoindolin-4-yl]-2-ethoxy-acetamide (C17H17N3O6) contains a flavonoid 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. 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.

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.
