Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N,N'-(Azanediylbis(9,10-dioxo-9,10-dihydroanthracene-4,1-diyl))dibenzamide.
N,N'-(Azanediylbis(9,10-dioxo-9,10-dihydroanthracene-4,1-diyl))dibenzamide (CAS 128-79-0) is a high-purity analytical reference standard with the molecular formula C42H25N3O6 and a molecular weight of 667.66 g/mol.
N,N'-(Azanediylbis(9,10-dioxo-9,10-dihydroanthracene-4,1-diyl))dibenzamide (C42H25N3O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N,N'-(Azanediylbis(9,10-dioxo-9,10-dihydroanthracene-4,1-diyl))dibenzamide 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.
