Chemical Structure
Description
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.
CATO supplies 1,4-Dihydroxy-5,8-bis((2-(methyl(phenyl)amino)ethyl)amino)anthracene-9,10-dione (CAS 70945-58-3), a certified reference material (molecular formula C32H32N4O4, MW 536.62 g/mol) for analytical method development and quality control.
The molecular framework of 1,4-Dihydroxy-5,8-bis((2-(methyl(phenyl)amino)ethyl)amino)anthracene-9,10-dione (C32H32N4O4) is characterized by a nitrogen-containing heterocyclic scaffold, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 1,4-Dihydroxy-5,8-bis((2-(methyl(phenyl)amino)ethyl)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.
