一般描述

偏高碘酸钠是有机合成中常用的氧化剂，用于氧化各种有机底物。它也可与其他氧化剂如四氧化锇、高锰酸钾等作共氧化剂。高碘酸钠的氧化发生在水介质中，但有机助溶剂用于不溶于水的有机基质。

应用

偏高碘酸钠可用作氧化剂，用于氧化：      
  • 1,2-二醇通过氧化裂解生成醛或酮。       在相转移催化剂的作用下，硫化物转化为亚砜。      
  • 二芳基、二烷基和芳基烷基硒化物转化为各自的硒氧化物。      
  • 酚类及其相应的醌类衍生物。
  • 酰基磷烷变成 α,β-二羰基化合物。

它也可用于：      
  • 选择性烯烃环氧化和烷烃羟基化，
  • 碳水化合物氧化。      
  • 芳香化合物的碘化。

可用于在进行生物素酰肼标记前氧化糖类的试剂

特点和优势

NaIO4是一种稳定、选择性的经济试剂，能够在温和的条件下反应。

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  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.
