Chemical Structure

(1S,1'S)-[1,1'-binaphthalene]-2,2'-diylbis(phenylmethanol) CAS 1281985-56-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 466.57 g/mol gives (1S,1'S)-[1,1'-binaphthalene]-2,2'-diylbis(phenylmethanol) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(1S,1'S)-[1,1'-binaphthalene]-2,2'-diylbis(phenylmethanol) (CAS 1281985-56-5) is a high-purity analytical reference standard with the molecular formula C34H26O2 and a molecular weight of 466.57 g/mol.

(1S,1'S)-[1,1'-binaphthalene]-2,2'-diylbis(phenylmethanol) (C34H26O2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
