Description
CATO manufactures 1,1'-Diamino-[2,2'-bianthracene]-9,9',10,10'-tetraone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 1,1'-Diamino-[2,2'-bianthracene]-9,9',10,10'-tetraone (CAS 6546-50-5), a certified reference material (molecular formula C28H16N2O4, MW 444.44 g/mol) for analytical method development and quality control.
The molecular framework of 1,1'-Diamino-[2,2'-bianthracene]-9,9',10,10'-tetraone (C28H16N2O4) 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).
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.
