Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 446.58 g/mol gives (S)-5,5',6,6',7,7',8,8'-Octahydro-3,3'-diphenyl-[1,1'-binaphthalene]-2,2'-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-5,5',6,6',7,7',8,8'-Octahydro-3,3'-diphenyl-[1,1'-binaphthalene]-2,2'-diol (CAS 575451-08-0) is a high-purity analytical reference standard with the molecular formula C32H30O2 and a molecular weight of 446.58 g/mol.
Structurally, (S)-5,5',6,6',7,7',8,8'-Octahydro-3,3'-diphenyl-[1,1'-binaphthalene]-2,2'-diol (C32H30O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 446.58 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
