2-[4-(3-Chlorophenyl)piperazin-1-yl]quinoxaline CAS 241146-70-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[4-(3-Chlorophenyl)piperazin-1-yl]quinoxaline.

2-[4-(3-Chlorophenyl)piperazin-1-yl]quinoxaline (CAS 241146-70-3) is a high-purity analytical reference standard with the molecular formula C18H17ClN4 and a molecular weight of 324.81 g/mol.

The molecular framework of 2-[4-(3-Chlorophenyl)piperazin-1-yl]quinoxaline (C18H17ClN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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.

As a certified reference material (CRM), 2-[4-(3-Chlorophenyl)piperazin-1-yl]quinoxaline 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.
