6,6'-Dimethoxy-[1,1'-binaphthalene]-2,2'-diol CAS 145372-06-1

Description

The occurrence of 6,6'-Dimethoxy-[1,1'-binaphthalene]-2,2'-diol is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6,6'-Dimethoxy-[1,1'-binaphthalene]-2,2'-diol (CAS 145372-06-1), molecular formula C22H18O4 and molecular weight 346.38 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C22H18O4, 6,6'-Dimethoxy-[1,1'-binaphthalene]-2,2'-diol contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 346.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
