5-(5,6-Dichloro-1-(2-chlorobenzyl)-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one CAS 338774-04-2

Description

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.

CATO supplies 5-(5,6-Dichloro-1-(2-chlorobenzyl)-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one (CAS 338774-04-2), a certified reference material (molecular formula C19H12Cl3N3O, MW 404.68 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-(5,6-Dichloro-1-(2-chlorobenzyl)-1H-benzo[d]imidazol-2-yl)pyridin-2(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 404.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
