Sodium Borohydride Description:
 
Sodium borohydride is an inorganic compound shown as a white to off-white fine crystalline powder or lump. Rapid reaction with methanol will produce hydrogen at room temperature. It is hygroscopic and easily deliquesced upon absorbing water. Boiling point: 500 °C (vacuum); melting point: 400 °C; soluble in water and lower alcohols, ammonia, insoluble in ether, benzene, hydrocarbons; relative density (water = 1): 1.07; Sodium borohydride is usually used as reducing agent in synthesis of inorganic and organic synthesis. Sodium borohydride has a strong selective reduction, being able to selectively reduce a carbonyl group is to a hydroxyl group without reacting with the carbon-carbon double bond and triple bond reaction. A small amount of sodium borohydride can restore the nitrile to the aldehyde with the excess amount being reduced to the amine.
 
Sodium Borohydride Uses:
 
The hydrogen of odium borohydride hydrogen here was-1 thus having a strong reducing property which can reduce some oxidative inorganic. It is mainly used for reducing-COOH to-CH2OH in organic synthesis. It plays such a significant role in organic synthesis that it is called as "universal reductant." It is a good reducing agent which has stable performance and selective reduction. It can be used as the reducing agents of aldehydes, ketones and acid chlorides; also as foaming agent for plastic materials, hydrogenating agent of making dihydrostreptomycin, intermediate of making potassium borohydride, raw materials in synthesizing borane, as well as the treatment agent of paper industry and mercury-containing waste water.
Sodium borohydride provides organic chemists a very convenient and mild means for reduction of aldehydes and ketones. Before this, people usually use metal/alcohol approach to reduce carbonyl compound. Sodium borohydride enables the reduction of carbonyl of aldehydes and ketones under very mild conditions to produce primary alcohols and secondary alcohols. Reduction procedure is as below: First dissolve the substrate in a solvent (typically methanol or ethanol), then cool with an ice bath. Finally add sodium borohydride powder to the mixture until the reaction is completed. The reaction process can be monitored by thin layer chromatography. If the solvent is not an alcohol, we need to additionally supply methanol or ethanol along with the reaction. Sodium borohydride is a reducing agent with medium strength, and thus exhibiting good chemical selectivity. It only reduces active aldehyde and ketone carbonyl group, and does not react with the ester, amide.
It is a good reducing agent which has stable performance and selective reduction. It can be used as the reducing agents of aldehydes, ketones and acid chlorides; also as foaming agent for plastic materials, hydrogenating agent of making dihydrostreptomycin, intermediate of making potassium borohydride, raw materials in synthesizing borane, as well as the treatment agent of paper industry and mercury-containing waste water.
Common used reducing agents. It can be used as the reducing agent of aldehydes, ketones and acid chlorides, foaming agent of plastic materials, hydrogenating agent for making dihydrostreptomycin, the intermediate of making potassium borohydride, raw materials of borane synthesis, treatment agent of paper industry and mercury-containing waste water, and also paper bleaching agent.
For the manufacture of other borohydride salts, reducing agents, bleaching wood pulp, and plastics blowing agent.
 
Nanocrystalline superlattices in gold colloid solution have been prepared by ligand-induction using AuCl3 reduced with sodium borohydride. 
Nucleophilic addition of hydride ion from sodium borohydride is an inexpensive alternative method for the Baylis-Hillman reaction to form [E]-α-methylcinnamic acids.
 
Sodium Borohydride is used as a reagent in the reduction of amino acids and their derivatives. Also used in the catalysis of ammonia borane dehydrogenation.
