Chemical Structure

Di-[3-((R)-2,2'-dihydroxy-1,1'-binaphthylmethyl)]ether, lanthanum(III) salt, tetrahydrofuran adduct CAS 321837-08-5 chemical structure

Description

The occurrence of Di-[3-((R)-2,2'-dihydroxy-1,1'-binaphthylmethyl)]ether, lanthanum(III) salt, tetrahydrofuran adduct 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.

Di-[3-((R)-2,2'-dihydroxy-1,1'-binaphthylmethyl)]ether, lanthanum(III) salt, tetrahydrofuran adduct (CAS 321837-08-5), molecular formula C42H27O5C4H12La and molecular weight 810.72 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Di-[3-((R)-2,2'-dihydroxy-1,1'-binaphthylmethyl)]ether, lanthanum(III) salt, tetrahydrofuran adduct is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 810.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
