SODIUM BOROHYDRIDE
Sodium borohydride — sodium tetrahydridoborate, NaBH4, CAS 16940-66-2 — is a white powder and one of the most convenient reducing agents in chemistry. In the laboratory it reduces aldehydes and ketones to alcohols cleanly in alcohol or water, tolerating esters and amides; industrially its largest use is producing sodium dithionite from sulphur dioxide for pulp bleaching and dyeing, and it also recovers precious metals from solution and generates hydrogen. RXSOL supplies the analytical grade (CAS 16940-66-2, EC 241-004-4) in 100 g to 1 kg packs and technical grade in drums; it reacts with water and acids to release hydrogen, so it is stored dry and sealed.
