Borane (BH3) is a chemical compound consisting of boron and hydrogen. 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 the synthesis of various compounds, including alcohols and amines. In its pure form, borane is highly reactive and can form stable complexes with other molecules. It is commonly encountered in the form of borane dimethyl sulfide (BMS), which is a more stable and manageable derivative. Due to its reactivity, borane must be handled with care in laboratory settings.
