Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,4,5,8-Tetraamino-2,7-bis(2-chlorophenoxy)anthracene-9,10-dione (CAS 88600-58-2), molecular formula C26H18Cl2N4O4 and molecular weight 521.35 g/mol, is a CATO reference standard with documented purity and traceability.
1,4,5,8-Tetraamino-2,7-bis(2-chlorophenoxy)anthracene-9,10-dione (C26H18Cl2N4O4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 1,4,5,8-Tetraamino-2,7-bis(2-chlorophenoxy)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.
