Chemical Structure
Description
The occurrence of Docusate Sodium USP Related Compound B Disodium Salt is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Docusate Sodium USP Related Compound B Disodium Salt (CAS 86878-53-7), molecular formula C12H20O7SNa and molecular weight 331.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Docusate Sodium USP Related Compound B Disodium Salt (C12H20O7SNa) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
As a certified reference material (CRM), Docusate Sodium USP Related Compound B Disodium Salt meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
