(R)-(+)-1,1'-Binaphthalene-2,2'-diyl-S,S-bis(N,N-dimethylcarbamate) (CAS 147923-23-7), molecular formula C26H24N2O2S2 and molecular weight 460.61 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (R)-(+)-1,1'-Binaphthalene-2,2'-diyl-S,S-bis(N,N-dimethylcarbamate) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 460.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
