(2R,4AR,8aR)-1,1,5,5-tetramethylhexahydro-1H-2,4a-methanonaphthalen-8(2H)-one (CAS 57456-74-3), molecular formula C15H24O and molecular weight 220.35 g/mol, is a CATO reference standard with documented purity and traceability.
(2R,4AR,8aR)-1,1,5,5-tetramethylhexahydro-1H-2,4a-methanonaphthalen-8(2H)-one (C15H24O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (2R,4AR,8aR)-1,1,5,5-tetramethylhexahydro-1H-2,4a-methanonaphthalen-8(2H)-one 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.
