N-(4-Chloro-2,5-dimethoxyphenyl)-2-(2,4-dioxo-1,3-diazaspiro[4.4]nonan-3-yl)acetamide CAS 853696-42-1

Description

The occurrence of N-(4-Chloro-2,5-dimethoxyphenyl)-2-(2,4-dioxo-1,3-diazaspiro[4.4]nonan-3-yl)acetamide is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-(4-Chloro-2,5-dimethoxyphenyl)-2-(2,4-dioxo-1,3-diazaspiro[4.4]nonan-3-yl)acetamide (CAS 853696-42-1), molecular formula C17H20ClN3O5 and molecular weight 381.81 g/mol, is a CATO reference standard with documented purity and traceability.

N-(4-Chloro-2,5-dimethoxyphenyl)-2-(2,4-dioxo-1,3-diazaspiro[4.4]nonan-3-yl)acetamide (C17H20ClN3O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
