Chemical Structure
Description
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.
(1R,2R)-Rel-N,N'-(cyclohexane-1,2-diyl)bis(2-(diphenylphosphino)-1-naphthamide) (CAS 178231-62-4) is a high-purity analytical reference standard with the molecular formula C52H44N2O2P2 and a molecular weight of 790.87 g/mol.
(1R,2R)-Rel-N,N'-(cyclohexane-1,2-diyl)bis(2-(diphenylphosphino)-1-naphthamide) (C52H44N2O2P2) contains a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), (1R,2R)-Rel-N,N'-(cyclohexane-1,2-diyl)bis(2-(diphenylphosphino)-1-naphthamide) 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.
