Specification
The Sodium Cyanoborohydride, with the CAS registry number 25895-60-7 and EINECS registry number 247-317-2, is also called Sodium cyanotrihydroborate. It is a kind of white solid which is moisture sensitive, and belongs to the following prodcut categories: Selectivity reducing agent; B (Classes of Boron Compounds); Classes of Metal Compounds; Na (Sodium) Compounds (excluding simple sodium salts); Reduction; Synthetic Organic Chemistry; Tetrahydroborates; Typical Metal Compounds; Borohydrides; Synthetic Reagents. And the molecular formula of the chemical is NaBH3CN. What's more, it should be stored under Argon.
The physical properties of Sodium Cyanoborohydride are as followings: (1)#H bond acceptors: 1; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 23.79 Å2.
Preparation and uses of Sodium Cyanoborohydride: It can be prepared either by treating sodium cyanide with borane, or by reacting sodium borohydride with mercury(II) cyanide. It is widely used in organic synthesis for the reduction of imines. And it is usually used as a mild reducing agent which converts imines to amines. And because of its selectivity, this chemical is ideal for reductive aminations at mildly basic solutions (pH 7-10).
You should be cautious while dealing with this chemical. It is a kind of highly flammable chemical which is also very toxic. If contacting with water, it will liberate extremely flammable gases, and explosive when mixed with oxidizing substances. And if contact with acids, it will liberate very toxic gas. And it may also cause burns. It is very toxic by inhalation, in contact with skin and if swallowed. It is very toxic to aquatic organisms, and may cause long-term adverse effects in the aquatic environment. Therefore, you had better take the following instructions: Keep locked up; Keep container dry; Wear suitable protective clothing, gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice; Avoid release to the environment. This material and/or its container must be disposed of as hazardous waste; Refer to special instructions safety data sheet; Do not mix with...(to be specified by the manufacturer); After contact with skin, wash immediately with plenty of... (to be specified by the manufacturer).
