Chemical Structure

N-Benzyl-N-[1-(4-bromophenyl)-2,5-dioxopyrrolidin-3-yl]-2-chloroacetamide CAS 1858241-22-1 chemical structure

Description

The molecular framework of N-Benzyl-N-[1-(4-bromophenyl)-2,5-dioxopyrrolidin-3-yl]-2-chloroacetamide (C19H16BrClN2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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).

N-Benzyl-N-[1-(4-bromophenyl)-2,5-dioxopyrrolidin-3-yl]-2-chloroacetamide (CAS 1858241-22-1), molecular formula C19H16BrClN2O3 and molecular weight 435.70 g/mol, is a CATO reference standard with documented purity and traceability.
