Sodium tellurite

Sodium tellurite (CAS 10102-20-2), also referenced as disodium tellurite in reagent catalogs, is an inorganic tellurium salt used primarily as a selective inhibitor.

Where is Sodium tellurite used?

• Microbiological and biochemical applications: trace-element source
• Diagnostic and research workflows: suppresses non-target bacterial growth
• Clinical and pharmaceutical microbiology: incorporated into selective culture media to isolate Corynebacterium diphtheriae and other tellurite-tolerant organisms
• Biotechnology research: tellurium source for studies of bacterial tellurite resistance mechanisms and tellurium nanoparticle biosynthesis
• Pharmaceutical-grade preparations are used in controlled laboratory settings to evaluate antimicrobial susceptibility and screen microbial strains for industrial fermentation programs.
• Analytical chemistry: reference standard material requiring certified tellurium content

Commercial specifications

• High-purity grades for research and pharmaceutical applications
• Packaging from small laboratory quantities to larger bulk formats
