Sodium Aurothiomalate - API Standards (CAS 12244-57-4), molecular formula C4H3AuO4SNa and molecular weight 367.08 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Sodium Aurothiomalate - API Standards (C4H3AuO4SNa) contains a carbohydrate-derived structure, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 367.08 g/mol, it falls into the moderately-high-molecular-weight range. 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).
CATO manufactures Sodium Aurothiomalate - API Standards 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.
