Product Name:Potassium tellurite trihydrate
English Name:Potassium tellurite trihydrate
CAS No.:20492-35-7
Aliases:Potassium tellurite
Molecular Formula:K2TeO3·3H2O
Physical Properties:White crystalline powder, readily soluble in water, slightly soluble in ethanol; aqueous solution is alkaline. Stable in air; loses water of crystallization upon heating to form the anhydrous salt.
Uses:Used in selective microbiological culture media as a common additive for isolating pathogens such as Corynebacterium diphtheriae. Also employed as an analytical reagent for the detection and separation of tellurates, and as a raw material in electroplating and the preparation of high-purity tellurium compounds.
Technical Specifications:
Purity: ≥99.9%
Molecular weight: 307.84 (as trihydrate)
Appearance: white crystalline or crystalline powder
Solubility: readily soluble in water, slightly soluble in ethanol
Storage: keep sealed and dry, avoid moisture
