  3. What is Sodium (meta)periodate, Product S1878, soluble in?

    We have tested the solubility of this compound in water at 100mg/mL; heat may be required to get it to dissolve at that concentration. Per the chemicals encyclopedia published by the Royal Society of Chemistry, it is also expected to be soluble in sulfuric, nitric and acetic acids.

  4. What can Sodium (meta)periodate, Product S1878, be used for?

    Sodium metaperiodate is used by synthetic chemists as an effective oxidant. It is a stable, specific, cost-effective reagent that is capable of reacting under mild conditions. It has been used to cleave vicinal diols to carbonyl compounds, convert sulfides into sulfoxides and oxidize primary and secondary halides to the corresponding aldehydes and ketones.

  5. How long is Sodium (meta)periodate, Product S1878, good for?

    Sodium metaperiodate is extremely stable at room temperature. Sigma-Aldrich assigns a recommended retest period of 8 years to this product as seen on the product's specification sheet.
