Description

CATO supplies 1-(3-Ethoxy-4-hydroxyphenyl)-2-(2-methoxyethyl)-5,7-dimethyl-1,2-dihydrochromeno[2,3-c]pyrrole-3,9-dione (CAS 880784-94-1), a certified reference material (molecular formula C24H25NO6, MW 423.46 g/mol) for analytical method development and quality control.

The molecular framework of 1-(3-Ethoxy-4-hydroxyphenyl)-2-(2-methoxyethyl)-5,7-dimethyl-1,2-dihydrochromeno[2,3-c]pyrrole-3,9-dione (C24H25NO6) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 1-(3-Ethoxy-4-hydroxyphenyl)-2-(2-methoxyethyl)-5,7-dimethyl-1,2-dihydrochromeno[2,3-c]pyrrole-3,9-dione 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.
