Sodium bismuthate

Sodium bismuthate (CAS 12232-99-4), formula NaBiO3, is a strong inorganic oxidizing agent.

Where is Sodium bismuthate used?

• Analytical chemistry: oxidizes manganese(II) ions to permanganate in qualitative analysis, a standard confirmatory test in QA laboratories
• Organic synthesis: selective oxidant converting specific functional groups under controlled conditions
• Pharmaceutical manufacturing: selective oxidation reactions
• Water treatment: biocidal activity against resistant microbial strains
• Specialty preservation formulations: sustained oxidative action against biofilm-forming organisms
• It is a yellow-to-orange powder at purities of 80–90% or higher.

Good to know: Technical grade is the most commonly traded specification; reagent-grade material is sourced for laboratory supply.

Commercial specifications

• Purity 80–90% or higher for technical-grade material
• Higher-purity grades for analytical use
