Chemical Structure
Description
(S)-2'-(Diphenylphosphino)-[1,1'-binaphthalen]-2-ol (C32H23OP) contains organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(S)-2'-(Diphenylphosphino)-[1,1'-binaphthalen]-2-ol (CAS 144868-15-5) is a high-purity analytical reference standard with the molecular formula C32H23OP and a molecular weight of 454.50 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
