(1aR,4aR,6S,7S,7aR,8R,11aS,E)-1,1,3,6-Tetramethyl-9-methylene-7-(nicotinoyloxy)-4-oxo-1a,4,4a,5,6,7,7a,8,9,10,11,11a-dodecahydro-1H-cyclopenta[a]cyclopropa[f][11]annulene-4a,8-diyl diacetate (CAS 218916-53-1), molecular formula C30H37NO7 and molecular weight 523.62 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (1aR,4aR,6S,7S,7aR,8R,11aS,E)-1,1,3,6-Tetramethyl-9-methylene-7-(nicotinoyloxy)-4-oxo-1a,4,4a,5,6,7,7a,8,9,10,11,11a-dodecahydro-1H-cyclopenta[a]cyclopropa[f][11]annulene-4a,8-diyl diacetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 523.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (1aR,4aR,6S,7S,7aR,8R,11aS,E)-1,1,3,6-Tetramethyl-9-methylene-7-(nicotinoyloxy)-4-oxo-1a,4,4a,5,6,7,7a,8,9,10,11,11a-dodecahydro-1H-cyclopenta[a]cyclopropa[f][11]annulene-4a,8-diyl diacetate 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.
