Chemical Structure
Description
The occurrence of (R)-5,5',6,6',7,7',8,8'-Octahydro-3,3'-bis(2,4,6-trimethylphenyl)-[1,1'-binaphthalene]-2,2'-diol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-5,5',6,6',7,7',8,8'-Octahydro-3,3'-bis(2,4,6-trimethylphenyl)-[1,1'-binaphthalene]-2,2'-diol (CAS 400027-51-2) is a high-purity analytical reference standard with the molecular formula C38H42O2 and a molecular weight of 530.74 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (R)-5,5',6,6',7,7',8,8'-Octahydro-3,3'-bis(2,4,6-trimethylphenyl)-[1,1'-binaphthalene]-2,2'-diol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 530.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
