一般描述
Sodium cyanoborohydride is a versatile reducing agent stable in aqueous solution at pH 7.2. It is a weaker reducing agent as compared to NaBH4. It effectively reduces Schiff bases. NaCNBH4 participates in the reductive methylation for the efficient and selective conversion of the ε-amino groups of lysyl residues in proteins to the mono- and dimethyl derivatives.
Review on sodium cyanoborohydride has been reported. It participates in selective reductions with NaCNBH3, modified with zinc chloride, with zinc iodide.

应用
Sodium cyanoborohydride may be used in the following studies:
- As reducing agent for the in vitro radiolabeling of proteins by reductive alkylation.
- Reduction of aldehydes and ketones.
- Selective deoxygenation of aldehydes and ketones.
- Preparation of colloidal gold particles of varying sizes.
其他说明
综述；使用 NaCNBH4 选择性还原，使用氯化锌改性；使用碘化锌
