Function:
Sodium cyanoborohydride is widely used in organic synthesis for the reduction of imines. It is a mild reducing agent that converts imines to amines. It can be used to exchange the oxygen for an amine group on the carbonyl carbon of aldehydes or ketones when reacted with chemical or a primary amine.
Sodium cyanoborohydride is the chemical compound with the formula NaBH3CN. It is a colourless salt, but commercial samples can appear tan. It is widely used in organic synthesis for the reduction of imines. The salt tolerates aqueous conditions.
