Sodium bismuthate

Sodium bismuthate (CAS 12232-99-4 ), also referenced by its formula NaBiO3, is a strong inorganic oxidizing agent used across analytical chemistry, pharmaceutical manufacturing, and specialty treatment processes.

Its high oxidizing potential makes it effective for selective oxidation reactions and biocidal applications where conventional oxidants are unsuitable for specific industrial or laboratory requirements.

In pharmaceutical and chemical synthesis, sodium bismuthate oxidizes manganese(II) ions to permanganate in qualitative analysis, which is a standard confirmatory test used in QA laboratories.

It functions as a selective oxidant in organic synthesis, converting specific functional groups under controlled conditions without broad reagent interference during the manufacturing process.

Water treatment applications leverage its biocidal activity against resistant microbial strains where conventional disinfectants show reduced efficacy in challenging environmental conditions.

Specialty formulations targeting preservation also incorporate sodium bismuthate where sustained oxidative action is required against biofilm-forming organisms in industrial systems.

Sodium bismuthate is supplied as a yellow-to-orange powder, typically at purities of 80–90% or higher for technical-grade material, with higher-purity grades available for analytical use.

Technical grade is the most commonly traded specification, though reagent-grade material is sourced for laboratory supply and bulk quantities for industrial procurement needs.
