Introduction

Sodium borohydride, also known as sodium tetrahydridoborate and sodium tetrahydroborate, is an inorganic compound. This white solid, usually encountered as a powder, is a versatile reducing agent that finds wide application in chemistry, both in the laboratory and on a technical scale. It has been tested as pre-treatment for pulping of wood, but is too costly to be commercialized. The compound is soluble in alcohols and certain ethers but reacts with water in the absence of a base.
