Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1,5-Bis((4-methoxyphenyl)amino)anthracene-9,10-dione (CAS 2944-16-3), a certified reference material (molecular formula C28H22N2O4, MW 450.49 g/mol) for analytical method development and quality control.
The molecular framework of 1,5-Bis((4-methoxyphenyl)amino)anthracene-9,10-dione (C28H22N2O4) 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 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).
As a certified reference material (CRM), 1,5-Bis((4-methoxyphenyl)amino)anthracene-9,10-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.
