2-(4-Chlorophenyl)-N-(2-(4-chlorophenyl)-2-oxoethyl)-N,N-dimethyl-2-oxoethan-1-aminium bromide CAS 241127-29-7

Description

As a certified reference material (CRM), 2-(4-Chlorophenyl)-N-(2-(4-chlorophenyl)-2-oxoethyl)-N,N-dimethyl-2-oxoethan-1-aminium bromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

2-(4-Chlorophenyl)-N-(2-(4-chlorophenyl)-2-oxoethyl)-N,N-dimethyl-2-oxoethan-1-aminium bromide (CAS 241127-29-7), molecular formula C18H18Cl2NO2Br and molecular weight 431.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(4-Chlorophenyl)-N-(2-(4-chlorophenyl)-2-oxoethyl)-N,N-dimethyl-2-oxoethan-1-aminium bromide (C18H18Cl2NO2Br) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
