N-(4-Isopropylphenyl)-2-(4-(4-methoxybenzylidene)-2,5-dioxoimidazolidin-1-yl)acetamide CAS 867311-85-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-Isopropylphenyl)-2-(4-(4-methoxybenzylidene)-2,5-dioxoimidazolidin-1-yl)acetamide.

N-(4-Isopropylphenyl)-2-(4-(4-methoxybenzylidene)-2,5-dioxoimidazolidin-1-yl)acetamide (CAS 867311-85-1), molecular formula C22H23N3O4 and molecular weight 393.44 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(4-Isopropylphenyl)-2-(4-(4-methoxybenzylidene)-2,5-dioxoimidazolidin-1-yl)acetamide (C22H23N3O4) is characterized by a flavonoid 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
