Applicazioni

Reducing agent for the preparation of plate-type palladium-zinc oxide catalys, reagent for chemical vapor generation and spectrometry determination of elements using amineboranes and cyanotrihydroborate(III) reagents. Catalyst for regioselective reductive opening of benzylidene acetal glycosides and polarity reversal.

Note

Moisture Sensitive, store away from water/moisture. Store in cool. Keep container tightly closed in a dry and well-ventilated place. Store away from oxidizing agent.
