Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-[(1R)-2'-(Diphenylphosphino)[1,1'-binaphthalen]-2-yl]- acetamide (CAS 278800-82-1) is a high-purity analytical reference standard with the molecular formula C34H26NOP and a molecular weight of 495.55 g/mol.
N-[(1R)-2'-(Diphenylphosphino)[1,1'-binaphthalen]-2-yl]- acetamide (C34H26NOP) contains a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), N-[(1R)-2'-(Diphenylphosphino)[1,1'-binaphthalen]-2-yl]- acetamide 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.
