Chemical Structure
Description
As a certified reference material (CRM), 1-Amino-2-bromo-4,8-dihydroxy-5-(methylamino)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.
1-Amino-2-bromo-4,8-dihydroxy-5-(methylamino)anthracene-9,10-dione (CAS 84560-12-3), molecular formula C15H11BrN2O4 and molecular weight 363.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Amino-2-bromo-4,8-dihydroxy-5-(methylamino)anthracene-9,10-dione (C15H11BrN2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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.
