Pentaborane

Use

Pentaborane is an extremely reactive reducing agent. It can ignite spontaneously in contact with air and many other materials. Reactions with oxygen are often violently explosive. Reacts with ammonia to form a diammoniate. Reacts on contact with water, oxidizers, halogens, including halogenated hydrocarbons. May sel-heat and ignite spontaneously in moist air, decomposes @ 150C. Hydrolyzes slowly with heat in water to form boric acid. Contact with solvents, such as ketones, ethers and esters form shock-sensitive compounds. Pentaborane is stable in hydrocarbon solvents, but forms shock sensitive solutions in most carbonyl containing solvents. Corrosive to natural rubber, some synthetic rubbers and to some lubricants. Avoid dimethyl sulfoxide, direct sunlight and sources of ignition.
