Borane is a chemical compound consisting of boron and hydrogen, with the formula BH3. It is a colorless gas at room temperature and is known for its strong reducing properties. Borane is often used in organic chemistry as a reagent for various reactions, including the reduction of carbonyl compounds. Due to its reactivity, borane must be handled with care, as it can form explosive mixtures with air. It is typically stored in special containers to prevent contact with moisture, which can lead to the formation of boric acid. Borane derivatives, such as trialkylboranes, are also important in synthetic chemistry.
