N,N'-((3aR,4S,7R,7aS)-5-(tert-butyl)-2,2-dimethyl-3a,4,7,7a-tetrahydrobenzo[d][1,3]dioxole-4,7-diyl)dibenzamide (CAS 1998128-24-7) is a high-purity analytical reference standard with the molecular formula C27H32N2O4 and a molecular weight of 448.55 g/mol.
Structurally, N,N'-((3aR,4S,7R,7aS)-5-(tert-butyl)-2,2-dimethyl-3a,4,7,7a-tetrahydrobenzo[d][1,3]dioxole-4,7-diyl)dibenzamide (C27H32N2O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 448.55 g/mol, it falls into the moderately-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).
As a certified reference material (CRM), N,N'-((3aR,4S,7R,7aS)-5-(tert-butyl)-2,2-dimethyl-3a,4,7,7a-tetrahydrobenzo[d][1,3]dioxole-4,7-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.
