Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N,N'-(9,10-Dioxo-9,10-dihydroanthracene-1,5-diyl)bis(2,3,4,5-tetrachlorobenzamide).
CATO supplies N,N'-(9,10-Dioxo-9,10-dihydroanthracene-1,5-diyl)bis(2,3,4,5-tetrachlorobenzamide) (CAS 27685-83-2), a certified reference material (molecular formula C28H10Cl8N2O4, MW 722.01 g/mol) for analytical method development and quality control.
Structurally, N,N'-(9,10-Dioxo-9,10-dihydroanthracene-1,5-diyl)bis(2,3,4,5-tetrachlorobenzamide) (C28H10Cl8N2O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 21.0, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 722.01 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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'-(9,10-Dioxo-9,10-dihydroanthracene-1,5-diyl)bis(2,3,4,5-tetrachlorobenzamide) 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.
