Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Ethyl 1-((1,3-dioxoisoindolin-2-yl)methyl)-6,7-dimethoxyisoquinoline-4-carboxylate (CAS 264188-67-2), a certified reference material (molecular formula C23H20N2O6, MW 420.41 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 1-((1,3-dioxoisoindolin-2-yl)methyl)-6,7-dimethoxyisoquinoline-4-carboxylate (C23H20N2O6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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 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.
