Reducing agent used in the prepn. of modified hop extract
BH4? is an excellent ligand for metal ions. Such borohydride complexes are often prepared by the action of NaBH4 (or the LiBH4) on the corresponding metal halide, e.g. Zr(BH4)4.; Sodium borohydride is a particularly dangerous laboratory reagent. It is highly corrosive, and will cause burns upon contact with any area of the body. It is harmful if swallowed, inhaled or absorbed through the skin. It is highly flammable and will react with water.; Sodium borohydride is an odorless white to gray-white microcrystalline powder which often forms lumps. It is soluble in water, with which it reacts vigorously.; Sodium borohydride is highly reactive, and supports combustion. It is a flammable solid. It can ignite in air in the presence of an open flame, and will continue to burn as hydrogen is evolved. It can react with water and steam to produce hydrogen, which is flammable. An explosion can occur by spontaneous ignition of the gases released from a saturated solution of sodium borohydride in dimethylformamide at 17 °C.; Sodium borohydride, also known as sodium tetrahydroborate, has the chemical formula NaBH4. This white solid, usually encountered as a powder, is a specialty reducing agent used in the manufacture of pharmaceuticals and other organic and inorganic compounds. It is soluble in methanol and water, but reacts with both in the absence of base. Sodium borohydride is found in alcoholic beverages.
