2-(4-(4-Chlorobenzyl)piperazin-1-yl)-1-(indolin-1-yl)ethan-1-one (CAS 240127-55-3) is a high-purity analytical reference standard with the molecular formula C21H24ClN3O and a molecular weight of 369.89 g/mol.
The molecular framework of 2-(4-(4-Chlorobenzyl)piperazin-1-yl)-1-(indolin-1-yl)ethan-1-one (C21H24ClN3O) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-(4-Chlorobenzyl)piperazin-1-yl)-1-(indolin-1-yl)ethan-1-one 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.
