Chemical Structure
Description
Sodium 2-(dicyclohexylphosphino)-2',6'-dimethoxybiphenyl-3'-sulfonate (C26H34NaO5PS) contains a steroid core, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Sodium 2-(dicyclohexylphosphino)-2',6'-dimethoxybiphenyl-3'-sulfonate (CAS 870245-75-3) is a high-purity analytical reference standard with the molecular formula C26H34NaO5PS and a molecular weight of 512.57 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
