Cas no 16940-66-2 Sodium borohydride Inorganic compound purity 99% Inorganic salts, borates China Wholesale Price Best Quality Nabh4 Powder Sodium-B-Orohydride

Sodium borohydride (Sodium borohydride), is an inorganic compound, the chemical formula is NaBH4, white to off-white crystalline powder, strong hygroscopicity, its alkaline solution is brownish yellow, is one of the most commonly used reducing agents. Soluble in water, liquid ammonia, amines, easily soluble in methanol, slightly soluble in ethanol, tetrahydrofuran, insoluble in ether, benzene, hydrocarbons.

It is stable in dry air, decomposes in humid air, and also decomposes under heating at 500°C. In general, sodium borohydride cannot reduce esters, amides, carboxylic acids and nitrile compounds, but when there is a heteroatom at the carbonyl α position of the ester, the ester can be reduced.

It is usually used as a reducing agent for aldehydes, ketones, and acid chlorides, as a foaming agent in the plastics industry, as a paper bleaching agent, and as a hydrogenating agent for the production of dihydrostreptomycin in the pharmaceutical industry.

Top Quality Sodium borohydrid CAS 16940-66 2:
Sodium borohydrid is a very strong reducing agent used in organic and biochemical reactions. Nanocrystalline superlattices in gold colloid solution have been prepared by ligand-induction using AuCl₃ reduced with sodium borohydrid.

Nucleophilic addition of hydride ion from sodium borohydrid is an inexpensive alternative method for the Baylis-Hillman reaction to form [E]-α-methylcinnamic acids.

Top Quality Sodium borohydrid CAS 16940-66 2 Application:

1.The principle application of sodium borohydrid is the production used as a bleaching agent for wood pulp and in the dyeing industry.
2. Sodium borohydrid , as water soluble reductant, is also mainly used in drug, pulp bleaching, recovery of noble metals and preventation of the occurrence of public nuisances caused by heavy metals.

It is reductant of carbonyl compound (aldehyde, ketone, acid, acid amide, acid anhydride, acid halogen, ester, enol ester, imide, lactone), carbonitriding chemicals (azide, diazo salts, hydrazone, imine, nitrile, oxime, nitro compound), peroxide and hydroperoxide;
3. Sodium borohydrid, is used to remove color, smell of organic chemicals, used to control pollution and recycle noble metals, the production of drug and fine chemical.
