Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1031.80 g/mol gives Potassium Sucrose Octasulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Potassium Sucrose Octasulfate (CAS 76578-81-9), molecular formula C12H14O35S8KH2O and molecular weight 1031.80 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Potassium Sucrose Octasulfate (C12H14O35S8KH2O) is characterized by a carbohydrate-derived structure, a sulfone group. 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 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.
As a certified reference material (CRM), Potassium Sucrose Octasulfate 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.
