Chemical Structure
Description
(S)-3,3'-Diphenyl-1,1'-binaphthalene-2,2'-diol (C32H22O2) 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).
(S)-3,3'-Diphenyl-1,1'-binaphthalene-2,2'-diol (CAS 102490-05-1) is a high-purity analytical reference standard with the molecular formula C32H22O2 and a molecular weight of 438.52 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.
