Chemical Structure
Description
CATO supplies (R)-3,3'-Bis(2,4,6-trimethylphenyl)-[1,1'-binaphthalene]-2,2'-diol (CAS 394737-30-5), a certified reference material (molecular formula C38H34O2, MW 522.68 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (R)-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 522.68 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).
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.
