Chemical Structure
Description
CATO supplies 3-((1-Methylpiperidin-4-yl)oxy)-1-phenylisoquinoline (CAS 89707-53-9), a certified reference material (molecular formula C21H22N2O, MW 318.41 g/mol) for analytical method development and quality control.
The molecular framework of 3-((1-Methylpiperidin-4-yl)oxy)-1-phenylisoquinoline (C21H22N2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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), 3-((1-Methylpiperidin-4-yl)oxy)-1-phenylisoquinoline 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.
