Chemical Structure
Description
The molecular framework of 2-chloro-1-[4-(2-methoxyethyl)piperazin-1-yl]ethan-1-one (C9H17ClN2O2) is characterized by an amide group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
2-chloro-1-[4-(2-methoxyethyl)piperazin-1-yl]ethan-1-one (CAS 131028-05-2) is a high-purity analytical reference standard with the molecular formula C9H17ClN2O2 and a molecular weight of 220.70 g/mol.
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.
