Sodium cyanoborohydride solution (C15-1226-556)

General description

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 e-amino groups of lysyl residues in proteins to the mono- and dimethyl derivatives.

Application

Reactant for:

• Direct conversion of heterocyclic aldehydes to esters (oxidizing behavior)
• Reductive amination reactions
• Intramolecular reductive cyclization reactions
• Reductions reactions
• Preparation of dicyanoborate-based ionic liquids as hypergolic fluids for bipropellants

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.
