Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-2-Hydroxy-2’-[(R)-hydroxy(1-naphthyl)methyl]-[1,1’-binaphthalene] (CAS 1498319-69-9) is a high-purity analytical reference standard with the molecular formula C31H22O2 and a molecular weight of 426.51 g/mol.
(S)-2-Hydroxy-2’-[(R)-hydroxy(1-naphthyl)methyl]-[1,1’-binaphthalene] (C31H22O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
