Sodium hydride, with the chemical formula NaH, is an inorganic salt. In organic synthesis, sodium hydride is mainly used as a strong base. Sodium hydride is typical of salt hydrides, i.e. it is composed of Na+ and H?, unlike molecular hydrides such as borane, methane, ammonia, and water. Sodium hydride is insoluble in organic solvents but soluble in molten metallic sodium, so almost all reactions involving sodium hydride occur on solid surfaces.
