Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 460.61 g/mol gives (1S)-O,O'-([1,1'-binaphthalene]-2,2'-diyl) bis(dimethylcarbamothioate) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(1S)-O,O'-([1,1'-binaphthalene]-2,2'-diyl) bis(dimethylcarbamothioate) (CAS 189084-88-6), molecular formula C26H24N2O2S2 and molecular weight 460.61 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1S)-O,O'-([1,1'-binaphthalene]-2,2'-diyl) bis(dimethylcarbamothioate) (C26H24N2O2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
