Description
As a certified reference material (CRM), 1,4-Diamino-2-bromo-3-(4-(pentyloxy)phenoxy)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.
1,4-Diamino-2-bromo-3-(4-(pentyloxy)phenoxy)anthracene-9,10-dione (CAS 89868-55-3) is a high-purity analytical reference standard with the molecular formula C25H23BrN2O4 and a molecular weight of 495.37 g/mol.
The molecular framework of 1,4-Diamino-2-bromo-3-(4-(pentyloxy)phenoxy)anthracene-9,10-dione (C25H23BrN2O4) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
