Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Bismuth Citrate (100 mg) (CAS 813-93-4), molecular formula C6H5BiO7 and molecular weight 398.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bismuth Citrate (100 mg) (C6H5BiO7) is characterized by a carbohydrate-derived structure. 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).
As a certified reference material (CRM), Bismuth Citrate (100 mg) 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.
