Chemical Structure
Description
CATO manufactures Bismuth Sodium Tartrate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Bismuth Sodium Tartrate (CAS 31586-77-3), molecular formula BiC4H4O6Na and molecular weight 380.04 g/mol, is a CATO reference standard with documented purity and traceability.
Bismuth Sodium Tartrate (BiC4H4O6Na) contains a carbohydrate-derived structure. It is notably hygroscopic, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
