Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,4,5-Triamino-2,6-bis(2,5-dichlorophenoxy)anthracene-9,10-dione (CAS 88600-50-4), molecular formula C26H15Cl4N3O4 and molecular weight 575.23 g/mol, is a CATO reference standard with documented purity and traceability.
1,4,5-Triamino-2,6-bis(2,5-dichlorophenoxy)anthracene-9,10-dione (C26H15Cl4N3O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
