Description
[(1R,3aR,4aR,6R,8aR,9S,9aS)-9-[(Diphenylamino)carbonyl]dodecahydro-1-methyl-3-oxonaphtho[2,3-c]furan-6-yl]-carbamic Acid Ethyl Ester (CAS 900161-12-8), molecular formula C29H34N2O5 and molecular weight 490.59 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, [(1R,3aR,4aR,6R,8aR,9S,9aS)-9-[(Diphenylamino)carbonyl]dodecahydro-1-methyl-3-oxonaphtho[2,3-c]furan-6-yl]-carbamic Acid Ethyl Ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 490.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), [(1R,3aR,4aR,6R,8aR,9S,9aS)-9-[(Diphenylamino)carbonyl]dodecahydro-1-methyl-3-oxonaphtho[2,3-c]furan-6-yl]-carbamic Acid Ethyl Ester 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.
