Description

General description

Sodium cyanoborohydride, also known as sodium cyanotrihydridoborate, is a mild reducing agent that is stable in acidic conditions. It is widely used in the selective reduction of aryl aldehydes and ketones.

Application

Reagent for selective reductions.

Sodium cyanoborohydride is used as a reagent: 

To convert the amino-functional Si₃N₄ surface to a reactive surface with aldehyde groups.
For coupling amino-modified oligonucleotide probes.
In the synthesis of a novel phenolate-bridged dilanthanum(III) complex of interest as a model for metalloproteins.
In the reductive amination of aldehydes and ketones, and in the reductive alkylation of amines.
