(S)-3,3'-Dibromo-1,1'-Binaphthalene-2,2'-sulfonimide CAS 1461735-85-2

Description

Compared with other compounds in its class, the molecular weight of 553.24 g/mol gives (S)-3,3'-Dibromo-1,1'-Binaphthalene-2,2'-sulfonimide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(S)-3,3'-Dibromo-1,1'-Binaphthalene-2,2'-sulfonimide (CAS 1461735-85-2) is a high-purity analytical reference standard with the molecular formula C20H11Br2NO4S2 and a molecular weight of 553.24 g/mol.

(S)-3,3'-Dibromo-1,1'-Binaphthalene-2,2'-sulfonimide (C20H11Br2NO4S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
