Chemical Structure

(4-(4-Aminophenyl)piperazin-1-yl)(5-chloro-2-methoxyphenyl)methanone CAS 892693-46-8 chemical structure

Description

The molecular framework of (4-(4-Aminophenyl)piperazin-1-yl)(5-chloro-2-methoxyphenyl)methanone (C18H20ClN3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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).

CATO supplies (4-(4-Aminophenyl)piperazin-1-yl)(5-chloro-2-methoxyphenyl)methanone (CAS 892693-46-8), a certified reference material (molecular formula C18H20ClN3O2, MW 345.82 g/mol) for analytical method development and quality control.

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.
